Embodiment Construction
[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.
[0055] Such as figure 1 As shown, the present embodiment provides a method for controlling the throttle signal of an electric vehicle, the control method is applied to an electric vehicle, and the control method includes the following steps:
[0056] Step 101, receiving a braking trigger signal and performing braking.
[0057] In this step, when the brake switch is triggered by the driver, the vehicle controller receives the brake trigger signal from the brake switch, and outputs a brake signal to the electric motor by responding to the brake trigger signal. The braking mechanism of the automobile, the braking signal is used to trigger the b...

The invention provides an electric automobile and a control method and system thereof. The control method comprises the following steps that a whole automobile controller receives a brake triggering signal and outputs a braking signal to a braking mechanism of the electric automobile by responding to the brake triggering signal, the braking signal is used for triggering the braking mechanism to perform braking. When the whole automobile controller receives an accelerator triggering signal, whether the state of receiving the accelerator triggering signal is continuous or not is judged, if yes,whether the time for outputting the braking signal exceeds preset continuing time or not is also judged, if yes, the whole automobile controller outputs an accelerator signal to an acceleration mechanism of the electric automobile by preferably responding to the accelerator triggering signal in a preset accelerator priority time period and stops braking signal output, and the accelerator signal isused for triggering the acceleration mechanism to output a driving torque to the electric automobile. By adopting the control method, an accelerator triggering signal is accurately and preferentiallyresponded in the delay time when a braking signal is closed, and accordingly the security coefficient and user experience of vehicles are improved.
Description
technical field [0001] The invention relates to the field of electric vehicle control, in particular to a priority control method and system between braking and acceleration of an electric vehicle. Background technique [0002] At present, for safety reasons, the vehicle controller of electric vehicles will follow the principle of braking priority when designing, that is, when there are both accelerator trigger signals and brake trigger signals, the vehicle controller will only respond to the brake trigger signal. When the driver depresses the accelerator and brake pedals at the same time, the vehicle does not output drive torque. [0003] The brake trigger signal of an electric vehicle measures digital quantities, that is, open or close, the brake signal is turned on after the brake pedal is stepped on, and the brake signal is turned off by the return spring after the brake pedal is released. However, in actual operation, there will be a certain delay between when the driv...
