[0038] The first embodiment of the present invention discloses a motor control method for a car door lock. This method is used in cars. Such as figure 1 As shown, the method includes the following steps:

[0039] Step S101: When it is detected that the car is in a parked state, if an instruction to open any door from inside the car is received, acquire the motion parameters of a moving object approaching the car from the rear of the car.

[0040] Wherein, the car is in the parking state can be determined in the following way: set the vehicle speed as V, when 0≤V<5km / h, and the gear position is P gear, then it is determined that the car is in the parking state.

[0041] The rear of the car can be directly behind, obliquely behind, etc., as long as it is located behind the rear of the car and has a longitudinal distance greater than 0 from the rear of the car (see below for the definition of the longitudinal distance).

[0042] The motion parameters at least include: the type...

[0064] The second embodiment of the present invention discloses a motor control method for a car door lock. This method is used in cars. Such as Figure 5 As shown, the method includes the following steps:

[0065] Step S501: When it is detected that the car is in a parked state, if an instruction to open any door from inside the car is received, acquire motion parameters of a moving object approaching the car from the rear of the car.

[0066] Step S502: If the lateral distance between the moving object and the car is not greater than the first safety distance, determine that the moving object has a risk of contacting the car.

[0067] Steps S501-S502 are the same as steps S101-S102, and will not be repeated here.

[0068] Step S503: If the lateral distance between the moving object and the car is greater than the second safety distance, determine that the risk type of the moving object contacting the car is scratch contact.

[0069]Wherein, the second safety distance is ...

[0088] The third embodiment of the present invention discloses a motor control method for a car door lock. This method is used in cars. Such as Figure 6 As shown, the method includes the following steps:

[0089] Step S601: When it is detected that the car is in a parked state, if an instruction to open any door from inside the car is received, acquire motion parameters of a moving object approaching the car from the rear of the car.

[0090] Step S602: If the lateral distance between the moving object and the car is not greater than the first safety distance, determine that the moving object has a risk of contacting the car.

[0091] Steps S601-S602 are the same as steps S101-S102, and will not be repeated here.

[0092] Step S603: If the lateral distance between the moving object and the car is not greater than the second safety distance, determine that the risk type of the moving object contacting the car is collision contact.

Abstract

The invention provides a motor control method and system for a car door lock, and a car. The motor control method comprises the steps that when it is detected that the car is in a parking state, if aninstruction for opening any car door from the interior of the car is received, motion parameters of a moving object getting close to the car from the rear portion of the car are obtained; if the transverse distance between the moving object and the car is not greater than the first safe distance, it is determined that the moving object has the risk of making contact with the car; the type of therisk of contact between the moving object and the car is determined according to the transverse distance between the moving object and the car; and a motor of the car door lock is controlled to be locked or unlocked according to the type and speed of the moving object, the longitudinal distance between the moving object and the car, and the type of the risk of contact between the moving object andthe car. According to the motor control method, the danger caused by the moving object behind the car to passengers can be prejudged according to the type of the moving object, thus the motor of thecar door lock is controlled to be locked or unlocked, and car door opening can be limited or unlimited, so that the danger generated when the passengers get off the car is reduced.

Description

technical field [0001] The invention relates to the technical field of motor vehicles, in particular to a motor control method and system for a door lock and an automobile. Background technique [0002] With the widespread use of motor vehicles, the driving environment of vehicles has become more complex, especially in urban road conditions. When passengers open the door and get off after parking, all kinds of pedestrians, motorcycles, bicycles, and cars coming from behind Waiting for a motorized or non-motorized vehicle makes the process even more dangerous and can result in damage to the vehicle or even life-threatening. Therefore, the problem of door opening and collision avoidance is an urgent problem of personnel safety protection that needs to be solved under the current complex road conditions. Contents of the invention [0003] In view of this, the present invention aims to propose a motor control method for a car door lock to solve the problem in the prior art th...
