Embodiment Construction
[0013] The basic structure of a hybrid electric vehicle is well known to those skilled in the art, and will not be repeated here. The brake pedal diagnosis method of the hybrid electric vehicle is mainly controlled by the HCU on the hybrid electric vehicle.
[0014] Such as figure 1 As shown, the method for diagnosing the brake pedal in this embodiment is divided into two different stages, through which the diagnosis of the brake pedal can be completed. The brake pedal needs two signals, the brake signal and the brake light signal, and both signals are switch values.
[0015] After the vehicle control system is powered on and until the system is powered off, the diagnosis of the brake pedal is always performed. In the initial state, the operator does not step on the brake pedal, and the brake pedal is in the idle state; when the brake pedal is stepped on, the two-way The brake pedal signal is output to the hybrid vehicle control system, and the hybrid vehicle control system ...
