Embodiment
In the implementation of described active adjustable system of electronic throttle, engine electric-controlled unit can make engine electric-controlled unit that multiple accelerator pedal position and engine target output torque corresponding relation are provided by the selection of following three kinds of mode identification of driver to different driving models.
Embodiment one
Referring to shown in Figure 1, first kind of mode is by increasing a rotary switch, re-using analogue signal input channel of engine electric-controlled unit and come the selection of identification of driver to different driving models.
The resistor network that comprises three switches in the described in the present embodiment rotary switch and be made of resistance R 1, R2, R3 is as the sensor of selecting different driving models.One end of each switch is corresponding respectively to be connected with an end of a resistance, the other end ground connection of three resistance, and the common port of rotary switch is connected with an analogue signal input channel of engine electric-controlled unit.Described rotary switch can be respectively applied for selects sports type, comfortable type and economical driving model.Certainly, more driving model can also be set select, need rotary switch to increase the number of combinations of switch and resistance like this for the driver.
When rotary switch is selected the sports type driving model, K switch A1 closure, K switch A2 and KA3 disconnect, and the central processing unit (CPU) in this moment engine electric-controlled unit reads the respective channel magnitude of voltage and is,
When rotary switch is selected the comfortable type driving model, K switch A2 closure, K switch A1 and KA3 disconnect, and the central processing unit (CPU) in this moment engine electric-controlled unit reads the respective channel magnitude of voltage and is,
When rotary switch is selected economical driving model, K switch A3 closure, K switch A1 and KA2 disconnect, and the central processing unit (CPU) in this moment engine electric-controlled unit reads the respective channel magnitude of voltage and is,
The different magnitude of voltage that central processing unit (CPU) reads according to the analogue signal input channel are distinguished the selection of driver to different driving models.
When the input voltage of analogue signal input channel was the 1.25V left and right sides, engine electric-controlled unit became sports type with the correspondence setting of accelerator pedal position and engine target output torque; Engine electric-controlled unit is realized the engine target output torque is controlled according to the sports type curve controlled electronic air throttle body among Fig. 4.Under having determined the travelling comfort pattern after the accelerator pedal signal software filtering time constant b, the accelerator pedal signal software filtering time constant a of motor pattern correspondence is configured to value less than b.Like this, under motor pattern, accelerator pedal signal software filtering effect can be weaker than comfort mode, has improved the dynamic response sensitivity of engine target output torque to the action of driver's throttle, makes vehicle drive get up to feel comparing motion.
When the input voltage of analogue signal input channel was the 2.50V left and right sides, engine electric-controlled unit became comfortable type with the correspondence setting of accelerator pedal position and engine target output torque; Engine electric-controlled unit is according to the comfortable type curve controlled electronic air throttle body among Fig. 4, realizes the control of engine target output torque, and with the software filtering time constant b of accelerator pedal position signal input channel as reference value.When the comfortable type pattern was worked, it is more moderate that the corresponding relation of accelerator pedal position and engine target output torque mates.The corresponding relation of comfortable type accelerator pedal position and engine target output torque can be used as the default relationship of vehicle motor control.
