- the region between the “normal power generation start threshold” and the “normal power generation limit threshold” shown in FIG. 2A is a charge amount range (SOC range) that allows charging based on the power generated by the engine 1 in the normal mode.
- SOC range charge amount range
- the SOC that allows charging of the generated power by the engine 1 is defined by the “normal power generation limit threshold” as the upper limit and the “normal power generation start threshold” as the lower limit.
- the change in SOC within the SOC range is depicted linearly, but it is not necessary to control so as to exhibit a linear behavior.
- the SOC range in the normal mode is defined by the “normal power generation limit threshold” and the “normal power generation start threshold”, the behavior of the SOC in between may be set appropriately.
- the regenerative power is charged in principle according to the traveling state, it is often the case that the behavior of the SOC exhibits a non-linear displacement in accordance with the regenerative power.
- the above-described 90% is set as the upper limit value of the SOC range, in consideration of the addition of the charge amount by the regenerative power (buffer for regenerative power),
- the power generation of the engine 1 may be controlled so that the SOC converges to about 60%.
- the upper limit value of the charge amount based on the regenerative power is also set to the same value as the above-mentioned "normal power generation limit threshold (90%)". Therefore, when the regenerative electric power is generated by the drive motor 6 when the SOC exceeds 90% in the normal mode, the generator 2 is driven to motor the engine 1 without charging the regenerative electric power, etc. To consume.
- the upper limit value of the charge amount based on the regenerative power does not necessarily have to be the same value as the "normal power generation limit threshold". For example, a value slightly larger than the "normal power generation limit threshold" It may be set separately as the upper limit value of.
- a regenerative braking force corresponding to an engine brake in a general engine-driven vehicle is generated.
- the manner mode is a mode that enables traveling with less noise than the normal mode.
- charging of the battery 4 based on the power generated by the generator 2 is not performed. Therefore, the vehicle in the manner mode does not drive the engine 1 for power generation, and travels quietly by the drive motor 6 which uses only the discharge power of the battery 4 as the power source. That is, the driver can intentionally drive the vehicle quietly by selecting the manner mode.
- the manner mode is released against the intention of the driver to drive the engine 1.
- driving of the engine 1 is required in the manner mode, mainly the requirements from the aspect of safety or environmental protection, etc., for example, the requirement for catalyst warm-up to secure the exhaust performance of the engine 1, This is the case, for example, when it is necessary to generate negative pressure for brake pedal assist.
- the charge mode is a mode in which the battery 4 is charged more positively than in the normal mode.
- the vehicle controller 10 preferentially executes the power generation by the engine 1 so that the charge amount of the battery 4 reaches a preset reference value. That is, while the power generation is performed in the normal mode according to the traveling state, the power generation by the engine 1 is performed in the charge mode according to the mode operation by the driver or the occupant. That is, the driver can intentionally increase the SOC of the battery 4 by causing the engine 1 to execute power generation by selecting the charge mode.
- the SOC at the start time of the manner mode to be selected thereafter can be increased, so that the travel distance in the manner mode can be improved. it can.
- FIG. 2B is a diagram for describing charge amount control (SOC control) of the battery 4 in the charge mode.
- the horizontal axis represents time, and the vertical axis represents SOC [%] of the battery 4.
- the solid line in the figure is the SOC of the battery 4.
- the vehicle controller 10 detects that the charge mode is selected via the mode SW, and starts power generation by the engine 1. That is, in the charge mode, in response to the driver selecting the charge mode, power generation by the engine 1 is forcibly performed, and charging of the battery 4 is started.
- the vehicle controller 10 detects that the SOC of the battery 4 has reached a predetermined rate, and stops power generation by the engine 1.
- the predetermined ratio of the SOCs to be compared is hereinafter referred to as "charge mode power generation limit threshold".
- the charge mode power generation limit threshold is set to a value smaller than the above-described normal power generation limit threshold.
- the charge mode power generation limit threshold in the present embodiment is, for example, 75%.
- charge mode power generation limit threshold In the charge mode, as described above, power generation by the engine 1 is actively executed according to the driver's request, and the SOC of the battery 4 can be intentionally increased. As an example of a situation in which such a charge mode is selected, it is assumed that the manner mode is selected as described above.
- the power generation may be limited.
- the upper limit threshold for prohibiting the charging of the battery 4 is defined from the viewpoint of battery protection, and when it exceeds the upper limit threshold, it rushes into the “charge prohibited section” at least the power generation of the engine 1 is prohibited.
- the threshold value entering the charge inhibition interval is 90% is described in the description of the normal mode described above, but the threshold value is also applied in the charge mode. That is, in the present embodiment, from the viewpoint of battery protection, regardless of the selected mode, an upper limit threshold (here, 90%, hereinafter referred to as “charge limit upper limit value”) for prohibiting charging to battery 4 is set. Ru.
- the engine 1 mounted on the vehicle needs to warm up the exhaust catalyst of the engine 1 in order to secure the exhaust (exhaust gas) performance equal to or higher than a predetermined level.
- the exhaust catalyst is configured to be warmed according to the number of rotations of the engine 1 and the magnitude of the torque when the engine 1 is driven. Therefore, when the temperature of the exhaust catalyst falls to a temperature at which the exhaust performance above the predetermined level can not be secured, catalyst warm-up for driving the engine 1 may be required in order to warm the exhaust catalyst.
- the SOC is “charge limit” during the charge mode.
- Exceeding the upper limit value makes it easy to enter the charging prohibited section. For example, when the SOC is forcibly increased to 89.9% in the charge mode, the SOC simply exceeds the charge limit upper limit value by generation of regenerative electric power in that state. As a result, the charge inhibition zone is entered during the charge mode, and power generation is restricted for a while, so that catalyst warm-up may be required immediately after starting the manner mode travel.
- the SOC of the battery 4 may be lowered due to the consumption of power during the charging prohibited section, and the SOC at the start of the following manner mode traveling may be reduced.
- charge mode power generation limit threshold is set to be the same as the "normal power generation limit threshold"
- the possibility of driving the engine 1 in response to the catalyst warm-up request during the manner mode traveling increases.
- a value smaller than the above-described “normal power generation limit threshold” is set as the “charge mode power generation limit threshold” in the present embodiment.
- a buffer for regenerative power can be provided for the upper limit value (90% in this example) set from the viewpoint of battery protection, so that it is possible to suppress entry into the charging prohibited section during the charge mode.
- the upper limit value 90% in this example
- the size of the buffer for regenerative power may be increased or decreased according to the vehicle speed. Specifically, since the amount of regenerative power tends to increase as the vehicle speed increases, the “charge mode power generation limit threshold value” is set to a smaller value as the vehicle speed increases.
- the engine 1 of the present embodiment is configured to select an operating point (operating point) with higher efficiency according to the SOC of the battery 4 or the like. Therefore, it is preferable that the engine 1 is controlled to be driven at an operating point more suitable for catalyst warm-up, even at catalyst warm-up. That is, the catalyst warm-up by the engine 1 is performed at a more efficient operating point by setting a value smaller than the “normal power generation limit threshold” in the “charge mode power generation limit threshold” in the present embodiment. be able to. As a result, power can be generated at the operating point suitable for raising the catalyst temperature, so that the frequency of catalyst warm-up can be suppressed.
- 75% which is the value of the charge mode power generation limit threshold value shown here, is an example, and may be appropriately adapted according to the characteristics of the engine 1, the battery 4 and the like.
- the “charge mode power generation start threshold” is a value that defines the lower limit of the SOC range in the charge mode, and is set to a value larger than the “normal power generation start threshold”. As one example, the “charge mode power generation start threshold” in the present embodiment is 70%.
- the “charge mode power generation start threshold” may also be referred to as a value defining the hysteresis width with respect to the “charge mode power generation limit threshold”.
- the vehicle controller 10 may lower the SOC below the “charge mode generation start threshold”.
- the power generation of the engine 1 is controlled so as not to occur.
- the SOC of the battery 4 can be maintained in a high state (here, 70% or more), so that the timing does not depend on the selected charge mode (even if it is too early).
- the traveling distance in the manner mode selected can be improved.
- FIG. 3 is a time chart showing the behavior of the SOC in the charge mode.
- the horizontal axis represents time, and the vertical axis represents SOC [%] of the battery 4.
- the solid line in the figure is the SOC of the battery 4.
- t1 to t3 in the drawing correspond to t1 to t3 in FIG. 2B.
- the vehicle controller 10 detects that the charge mode has been selected via the mode SW, and forcibly starts power generation by the engine 1.
- the power generation by the engine 1 started at time t1 is continued in principle until the SOC reaches the "charge mode power generation limit threshold" (time t2).
- the generator 2 is driven by battery power even in the charge mode to generate negative pressure in the intake passage of the engine. Motoring control may be performed to operate the.
- the vehicle controller 10 detects that the SOC of the battery 4 has reached the “charge mode power generation limitation threshold”, and stops the power generation by the engine 1. After the power generation by the engine 1 is stopped, the drive motor 6 is driven or auxiliary devices (not shown) are operated to consume the power of the battery 4 and the SOC gradually decreases.
- the vehicle controller 10 detects that the SOC of the battery 4 has fallen below the “charge mode power generation start threshold”, and starts power generation by the engine 1. Power generation by the engine 1 started at time t3 is continued in principle until the SOC reaches the "charge mode power generation limit threshold" (time t4).
- time t4 similarly to time t2, it is detected that the SOC of the battery 4 has reached the “charge mode generation limit threshold value”, and power generation by the engine 1 is prohibited. Also at time t5, power generation by the engine 1 is started as at time t3. Then, after time t5, as long as the charge mode is selected, control is performed so that the SOC of battery 4 is maintained within the SOC range, as in time t2 to t5.
- the vehicle controller 10 starts power generation by the engine 1 according to the mode operation for selecting the charge mode, and sets the SOC of the battery 4 to the "charge mode power generation limit threshold". Force increase until reaching. Then, after the SOC of the battery 4 reaches the “charge mode generation limit threshold”, the SOC of the battery 4 is defined by the “charge mode generation limit threshold” and the “charge mode generation start threshold”. The power generation by the engine 1 is controlled so as to fall within the range.
- the SOC in the charge mode can be maintained in a high state (here, 70% or more), so the traveling distance in the following manner mode traveling can be improved regardless of the timing for selecting the charge mode. .
- the SOC in the charge mode to the "charge mode power generation limit threshold" set to a value lower than the “charge limit upper limit value” or less, a buffer for regenerative power can be secured. While the charge amount of the battery 4 is increased according to the charge request, it is possible to suppress that the power generation is inhibited for a certain period due to the charging of the regenerative power. As a result, when the manner mode traveling is started after the charge mode is turned off, the possibility that the engine 1 needs to be driven according to the request for catalyst warm-up can be reduced.
- the engine 1 since the upper limit value of the SOC range of the battery 4 is set in consideration of the efficient operating point of the engine 1, the engine 1 is driven according to the request for catalyst warm-up after the charge mode.
