Abstract

The invention discloses a kind of electric vehicle throttle sensitivity regulating systems, the present invention by control system of electric automobile increase by one auxiliary setting, so as to for " accelerator pedal position speed motor output dynamic characteristics " correspondence provide one can consecutive variations parameter.By the weighting of the parameter, " throttle steps on position speed motor target output torque relationship " can accordingly be changed in safe range, so as to fulfill the different electrodeless adjustments driven and felt.The parameter adjusted is cured and is stored up in Installed System Memory, then by face identification system, reaches automatic vehicle identification driver, provides the purpose of its desired driving performance.

Description

A kind of electric vehicle throttle sensitivity regulating system
Technical field
The present invention relates to a kind of electric vehicle throttle sensitivity regulating systems.
Background technology
Common electric vehicle gas pedal control technology is only capable of providing a kind of " accelerator pedal position-speed-motor output The correspondence of dynamic characteristics " can not meet the individual demand of driver.
Invention content
The object of the present invention is to provide a kind of electric vehicle throttle sensitivity regulating systems.
The technical solution adopted by the present invention is：A kind of electric vehicle throttle sensitivity regulating system, it is characterized in that：Including face Identification device, ECU, switch-operated response control, battery pack block and motor being driven, all system units are connected based on CAN bus, Work step is as follows：
1), the hand input-data on switch-operated response control is driven, the data are by CAN bus input ECU storages；
2), driver's face feature is recorded into the data in ECU and step 1) by face identification device and is arranged in pairs or groups；
3), ECU sets battery pack output voltage, Jin Ergai when accelerator pedal position is identical by the data in step 1) Become the output torque of motor, the ride characteristic of vehicle is made to be consistent with data；
4) data, set in above-mentioned steps are saved into ECU, and when driver drives again, stored data can be certainly Dynamic matching runs and can adjust and preserve again, is adjusted so as to fulfill the intelligence of driving performance.
As a further improvement on the present invention, ECU buckets cross CAN bus and are also connected with corresponding parameter displaying device.
As a further improvement on the present invention, switch-operated response control is driven to data modification using plug-in ECU, it is plug-in The signal that each sensor is fed back to ECU by ECU intercepts, and modifies, will surpass originally for the signal for needing to adjust The signal for crossing the genuine ECU accreditation upper limits becomes normal signal input genuine ECU, and ECU sets genuine after receiving normal signal Execution program export to plug-in ECU, at this moment plug-in ECU again modifies signal.
The beneficial effects of the invention are as follows：The present invention is set by increasing an auxiliary in control system of electric automobile, from And for " accelerator pedal position-speed-motor output dynamic characteristics " correspondence provide one can consecutive variations parameter.Through The weighting of the parameter is crossed, " throttle steps on position-speed-motor target output torque relationship " can obtain corresponding in safe range Change, so as to fulfill it is different drive feel electrodeless adjustments.The parameter adjusted is cured and is stored up in Installed System Memory, then By face identification system, reach automatic vehicle identification driver, the purpose of its desired driving performance is provided.
Description of the drawings
Fig. 1 is schematic diagram of the present invention.
Specific embodiment
As shown in Figure 1, a kind of electric vehicle throttle sensitivity regulating system, it is characterized in that：Including face identification device, ECU, Switch-operated response control, battery pack block and motor are driven, all system units are connected based on CAN bus, and work step is as follows：
1), the hand input-data on switch-operated response control is driven, the data are by CAN bus input ECU storages；
2), driver's face feature is recorded into the data in ECU and step 1) by face identification device and is arranged in pairs or groups；
3), ECU sets battery pack output voltage, Jin Ergai when accelerator pedal position is identical by the data in step 1) Become the output torque of motor, the ride characteristic of vehicle is made to be consistent with data；
4) data, set in above-mentioned steps are saved into ECU, and when driver drives again, stored data can be certainly Dynamic matching runs and can adjust and preserve again, is adjusted so as to fulfill the intelligence of driving performance.
The ECU buckets cross CAN bus and are also connected with corresponding parameter displaying device, and driver can directly show in parameter Setting data are checked on device.
ECU data is changed by driving switch-operated response control to data modification, using plug-in ECU, plug-in ECU will be each The signal that sensor feeds back to ECU is intercepted, and is modified for the signal for needing to adjust, will will be more than genuine ECU originally The signal of the accreditation upper limit becomes normal signal input genuine ECU, ECU and receives the execution program for setting genuine after normal signal Output is to plug-in ECU, and at this moment plug-in ECU again modifies signal.
Embodiments of the present invention are described above, but the present invention is not limited to the above embodiment, in affiliated skill In the knowledge that art field those of ordinary skill has, it can also be made under the premise of present inventive concept is not departed from various Variation.
