[0003] However, when the user actually wants to mount the R gear, but mistakenly mounts the D gear, the vehicle itself will not recognize whether it should be mounted to the D gear, but only drives the gear shift strategy according to the driving request, without considering external environmental factors; Or when the vision is not clear at night, if there is an obstacle within the dangerous distance ahead, but the user does not notice it, the user will forcibly mount the D gear, resulting in safety problems.

[0028] see figure 1 , figure 1 It is a schematic flowchart of a method for starting a car provided by the first embodiment of the present invention. In an automatic transmission car, when the user changes the gear position of the car through the shift lever, the TCU (Transmission Control Unit, automatic transmission control unit) feeds back the shift request of the target gear that the user wants to change through the shift lever to the VCU (Vehicle control unit, vehicle controller), at this time, the VCU will judge whether the current self-condition parameters of the vehicle meet the shift conditions. If the shift conditions are met, the VCU sends an instruction to the TVU to execute the shift request, and the TCU will send the The current gear is switched to the target gear, and the user releases the brake to complete the start.

[0029] This shift strategy is only based on the user's intention, and then combined with the current actual state of the car to complete the shi...

[0084] Image 6 , Image 6 It is a schematic structural block diagram of an automobile control system 10 provided in the second embodiment of the present invention. In this embodiment, the vehicle control system 10 may include a trajectory prediction module 200 , a distance detection module 500 , a judging module 600 and a reaction module 700 .

[0085] The trajectory prediction module 200 can be used to judge the vehicle's trajectory according to the user's gear shift request.

[0086] In this embodiment, the trajectory prediction module 200 may be used to execute step S200.

[0087] The distance detection module 500 may be used to collect distances of obstacles on the vehicle's travel track to generate a starting distance, which represents the current distance of the vehicle to obstacles on its travel track.

[0088] In this embodiment, the distance detection module 500 may be used to execute step S500.

[0089] The judging module 600 may be used to judge whether the sta...

[0112] The third embodiment of the present invention provides an automobile (not shown in the figure), which includes the automobile control system 10 provided in the above-mentioned second embodiment, and is used to implement the automobile control system 10 provided in the above-mentioned first embodiment. start method.

[0113] For brief description, for the parts not mentioned in this embodiment, reference may be made to the above-mentioned first embodiment and second embodiment.

[0114] To sum up, in the method for starting a car, the control system and the car provided by the embodiments of the present invention, when the VCU obtains the user's shift request, the direction of travel of the car represented by the shift request and the steering direction of the car and other parameters to generate the traveling track of the car. When it is judged that there is no obstacle within the first preset distance in the traveling track, it is determined that the current situation ...

Abstract

The embodiment of the invention provides an automobile starting method, a control system and an automobile, and relates to the technical field of automobile control. The method comprises the steps ofreceiving a gear shifting request from a user when the automobile is started, generating a travel trajectory of the automobile according to the gear shifting request, collecting the distance between the automobile and an obstacle on the travel trajectory of the automobile to generate a starting distance, determining whether the starting distance is greater than a first preset distance, and executing the gear shifting request to complete the starting of the automobile when the starting distance is greater than the first preset distance. The automobile starting method, the control system and theautomobile provided by the embodiment of the invention can determine whether current surroundings of the automobile conform to a target gear position which is requested for shifting when the automobile is started, so as to reduce the occurrence of traffic accidents.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a method for starting an automobile, a control system and the automobile. Background technique [0002] Under normal circumstances, the TCU mainly executes gear shifting according to the shift command of the VCU and the state of the transmission itself. For example, when the user mounts the D gear, the TCU will feed back the request to mount the D gear to the VCU. After the VCU thinks that the conditions are met, it will send an execution request to the TCU. The TCU executes the D gear, and then the user releases the brake to drive the vehicle. . [0003] However, when the user actually wants to mount the R gear, but mistakenly mounts the D gear, the vehicle itself will not recognize whether it should be mounted to the D gear, but only drives the gear shift strategy according to the driving request, without considering external environmental factors; Or when the line...
