The invention discloses a new energy automobile motor control anti-slip control method and system, and belongs to the technical field of automobiles, and the method comprises the steps: 1, collecting the state information of an automobile, judging whether the automobile is in a starting state or a parking state based on the state information of the automobile, and carrying out the anti-slip mode switching in different corresponding states; 2, when the vehicle is in the starting state, gear information is obtained, and whether the vehicle is in a forward gear or a reverse gear is judged; monitoring the rotating speed of the motor according to the vehicle gear information, and judging whether the motor is a positive value or a negative value; according to the positive value or negative value information of the motor, judging whether to enter an anti-slip mode or not; thirdly, when the vehicle is in the parking state, whether torque exists in a motor or not is monitored, and whether the vehicle enters the anti-slope-sliding mode or not is judged according to whether torque exists or not; and 4, when the vehicle is in the parking state, the wheel state is monitored, and whether the vehicle enters the slope sliding prevention mode or not is judged according to the wheel state. According to the control method and system, whether the vehicle slides or not can be monitored conveniently during driving or parking or not through the torque of the motor, response is made in time, braking is conducted on the vehicle, and a vehicle owner is remotely reminded.
本发明公开了一种新能源汽车电机控制防溜坡控制方法及系统,属于汽车技术领域,包括:步骤一、采集车辆状态信息,并基于车辆状态信息判断车辆为启动状态或驻车状态,并进行相应不同状态下的防溜坡模式切换;步骤二、当车辆为启动状态时,获取档位信息,进行判断车辆为前进挡或倒车挡;根据车辆档位信息进行监测电机转速,并判断电机为正值或负值;根据电机的正值或负值信息,进行判断是否进入到防溜坡模式中;步骤三、当车辆为驻车状态时,监测电机是否存在扭矩,并根据是否存在扭矩判断是否进入防溜坡模式中;步骤四、当车辆为驻车状态时,监测车轮状态,并根据车轮状态判断是否进入防溜坡模式中。该控制方法及系统便于在行车时、驻车时或者不通过电机的扭矩进行监测车辆是否发生溜车现象,并及时做出反应,在车辆上进行制动和远程提醒车主。
