Embodiment Construction
[0039] During the process of implementing the present application, the inventors found that the running stability of the current vehicle is relatively low.
[0040]In view of the above problems, the embodiment of the present application provides a vehicle operation control method, by first dividing the preset operation route of the vehicle into different operation sections according to the slope and the maximum speed limit, and then according to the resistance in each operation section Acceleration, preset driving acceleration and slope acceleration are calculated to obtain the actual running acceleration of the vehicle when passing through each running section, as well as the running time in each running section, and then determine the vehicle's expected speed according to multiple running accelerations and multiple running times. Set the number of operating mode switching times in the operating route, and finally when the obtained operating mode switching times are less than ...

The embodiment of the invention provides a vehicle operation control method and system and computer equipment. According to the scheme, the vehicle operation control method comprises the steps that a preset operation route of vehicle operation is divided into different operation road sections according to the gradient and the highest speed limit, and then the actual operation acceleration and the operation duration of the vehicle when the vehicle passes through each operation road section are obtained through calculation; and according to the multiple operation accelerations and the multiple operation durations, the working condition switching frequency of the vehicle in the preset operation route is determined, and finally when the obtained working condition switching frequency is smaller than a preset threshold value, the vehicle is controlled to operate on the preset route based on the operation acceleration and the operation duration corresponding to the working condition switching frequency. According to the invention, a technical problem that in the prior art, the running stability of an existing vehicle is low is solved, and the technical effect of improving the running stability of the vehicle is achieved.
Description
technical field [0001] The present application relates to the technical field of vehicle control, in particular, to a vehicle operation control method, system and computer equipment. Background technique [0002] With the vigorous development of urban rail transit in my country, automated driving has become a hot spot in current vehicle research. In automated driving, the determination of operating conditions is mainly by means of prediction: read the map data in the vehicle operating route in advance, determine various influencing factors of the vehicle in the operating route according to the map data, and then combine various influencing factors through The operating conditions of the vehicle in the preset route are predicted by online trial calculation, and finally the vehicle is controlled to run in the operating route based on each operating condition. [0003] However, frequently adjusting the working conditions during the running of the vehicle will easily lead to a ...
