The invention discloses a four-wheel indirect tire pressure detection method based on the motor wheel speed of an electric vehicle, which can judge whether the electric vehicle is in a straight running state, eliminate the error of the motor wheel speed signal of the four wheels of the electric vehicle, and filter the average value of the motor wheel speed signal, Set the reference number, set the corresponding critical value according to the calculated radius analysis value, set the reference number sequence, then set the reference number according to the reference sequence, and store the data in the data storage unit Perform statistics on the reference number, calculate the probability distribution, judge the low pressure condition of the vehicle tire according to the probability distribution of the reference number, compare the signal collected by the vehicle acceleration sensor with the acceleration of the motor wheel speed signal, set the corresponding threshold, and verify the four The tire pressure condition of the wheels. The invention provides an indirect tire pressure detection method based on the perimeter method. The processed wheel speed signal can be directly used to judge the low pressure information of the tire and give a low pressure alarm.
Description
technical field [0001] The invention relates to a tire pressure detection method, in particular to a four-wheel indirect tire pressure detection method based on the wheel speed of an electric vehicle motor, and belongs to the field of automobile control. Background technique [0002] From the perspective of safe driving, low tire pressure will lead to increased fuel consumption, weakened braking performance, abnormal wear on both sides of the tread, and easy damage to the sidewall. . The tire pressure is too high, and the bumps on the ground will cause the body to beat too much, damage the suspension system of the car, and cause problems such as uncomfortable driving. Therefore, car owners should develop a good habit of checking the tire pressure by themselves. Always pay attention to the value of tire pressure monitoring. It is best to refer to the standard tire pressure value given by the original car manufacturer, which can not only prolong the life of the tire, but also...
