Summary: | The invention discloses a hybrid vehicle idle charging slope sliding prevention control method. After a vehicle controller detects that a vehicle enters an idling state, whether idle charging entering conditions are satisfied nor not is detected first; the idle charging entering conditions comprise that 1, the vehicle is static, 2, the value of the state of charge (SOC) of a power battery is lower than a set maximum value, 3, a gearbox is in a P/N gear or a brake pedal is stepped down, 4, an engine operation state is allowed, and 5, a transmission chain is opened; and when the idle charging entering conditions are all satisfied, a slope angle condition is judged in the following steps of 1, when an ESP signal is valid and the vehicle is static, enabling the ESP to transmit a vehicle longitudinal acceleration coefficient signal to the vehicle controller, and enabling the vehicle controller to calculate a slope angle of approximately equal to 57.3*a, wherein a is a vehicle longitudinal acceleration coefficient, |
