Embodiment 1

[0023] This embodiment provides an automatic anti-rolling method for a pure electric vehicle, wherein the pure electric vehicle includes a battery, a motor, a pressure sensor, a gradient sensor, a handle sensor, a brake pedal sensor and an accelerator pedal sensor.

[0024] The battery is connected to the motor through an inverter, so as to provide power to the motor under the control of the vehicle controller; wherein the motor is used to drive the vehicle forward and backward.

[0025] The pressure sensor is used to detect the pressure of the driver's seat, and transmit the pressure signal to the vehicle controller, and the vehicle controller judges whether there is a driver on the driver's seat through the pressure; that is, when When the pressure of the driver's seat detected by the pressure sensor is greater than a certain threshold, it is judged that there is a driver (people) on the driver's seat; and when the pressure of the driver's seat detected by the pressure sensor...

Abstract

The invention discloses an automatic anti-vehicle-sliding method for a full electric vehicle. According to the automatic anti-vehicle-sliding method for the full electric vehicle, the conditions that whether a person exists on a driving seat or not, whether a motor is supplied with power or not, whether a handbrake is strained or not, whether the parking position of the full electric vehicle has gradient or not, and whether the motor rotates or not are judged, and when no parson exists on the driving seat, the motor is supplied with power, the handbrake is not strained, the parking position of the full electric vehicle has gradient, and the motor rotates, controlling over the motor torque is achieved, so that vehicle is prevented from sliding, and the phenomenon that vehicle sliding occurs during unmanned driving of the vehicle is avoided.

Description

technical field [0001] The invention relates to a control method for pure electric vehicles, in particular to an automatic anti-rolling method for pure electric vehicles. Background technique [0002] After the vehicle has come to a complete stop on a steep road and starts uphill again, regardless of whether the driving model is manual or automatic, if the handbrake is not used for auxiliary braking, once the right foot is released from the footbrake, the vehicle will experience varying degrees of vibration. Car slipping backwards can easily lead to traffic accidents. Therefore, before the vehicle starts on a slope, the driver usually pulls on the handbrake to keep the vehicle stationary, releases the brake pedal and then quickly depresses the accelerator pedal, and releases the handbrake while the vehicle is starting. This operation greatly increases the difficulty of driving the vehicle. . The existing hill start control function is a control function developed to simpli...
