Embodiment 1
[0043] see figure 1 , figure 2 , a virtual P gear parking slope and anti-slope control method for a new energy vehicle, including slope parking control, and the slope parking control is specifically carried out according to the following steps:
[0044] A1. The vehicle controller VCU judges whether the received current gear signal is a P gear signal. If so, control the motor controller MCU to enter the virtual P gear mode, and then enter step A2. If not, press the current gear signal to continue driving;
[0045] A2, the motor controller MCU judges whether a hand brake or a brake signal is received, if so, park the vehicle through the hand brake or the brake, if not, realize parking through the virtual P mode of the motor controller MCU;
[0046] Wherein, the realization of parking through the virtual P gear mode of the motor controller MCU is specifically:
[0047] The motor controller MCU first enters the speed control mode and controls the motor torque to be cleared, an...
Embodiment 2
[0051] The difference with embodiment 1 is:
[0052] see image 3 , Figure 4 , the method also includes anti-slope control, the anti-slope control is located after the standing slope control, and the anti-slope control is specifically: the motor controller MCU detects that the current gear signal is a D gear or R gear signal And if the handbrake, brake or accelerator signal is not detected, judge whether the motor has a speed and whether the direction of the motor speed is opposite to the current gear signal. If there is a speed and the direction of the speed is opposite to the current gear signal, enter the anti-slope mode , if not, enter the creeping driving mode;
[0053] The anti-slope mode is specifically: the motor controller MCU first opens the anti-slope function, and then closes the anti-slope function after T seconds, and exits the anti-slope mode after the above steps circulate N times, wherein, N=3, The anti-slope function is that the motor controller MCU appli...
