Pure electric bus self-adaptive cruise longitudinal control method and device and electronic equipment

The invention belongs to the technical field of pure electric bus control, and provides a pure electric bus self-adaptive cruise longitudinal control method and device and electronic equipment. The control method comprises the following steps: S1, calculating the safe vehicle distance and the emergency braking critical distance; s2, judging whether the vehicle is in a constant-speed cruise mode or a vehicle-following cruise mode; s3, calculating an expected longitudinal acceleration in a constant-speed cruise mode based on PID control or calculating an expected longitudinal acceleration in a vehicle-following cruise mode based on model predictive control; s4, determining the switching driving or braking state of the vehicle; and S5, converting the expected longitudinal acceleration into the corresponding motor driving torque or the corresponding vehicle braking force, and completing control over the vehicle. According to the control method, parameter calibration does not need to be conducted on the gain coeff
