Embodiment

[0045] This embodiment provides a control method for driving a commercial vehicle on mountain roads, see figure 1 , the control method for driving a commercial vehicle on a mountain road includes the following steps:

[0046]Obtain the vehicle's current speed, driving force, current acceleration and the slope information of the vehicle;

[0047] Calculate the current vehicle weight of the vehicle according to the current vehicle speed, driving force, current acceleration and slope information;

[0048] Determine the target acceleration according to the vehicle's current vehicle weight, accelerator opening, current vehicle speed and driving experience database, wherein the driving experience database includes the corresponding relationship between vehicle weight, accelerator opening, current vehicle speed and target acceleration;

[0049] According to the current acceleration and the target acceleration, judge whether torque compensation is needed;

[0050] If torque compensa...

Abstract

The invention discloses a commercial vehicle mountain road condition driving control method and system, commercial vehicle mountain road condition driving control equipment and a medium. The commercial vehicle mountain road condition driving control method comprises the following steps: obtaining a current vehicle speed, a driving force and current acceleration of a vehicle and ramp information where the vehicle is located; calculating current whole vehicle weight of the vehicle according to the current vehicle speed, the driving force, the current acceleration and the ramp information; acquiring accelerator opening information; determining a target acceleration according to the current vehicle weight, accelerator opening degree, current vehicle speed and a driving experience database of the vehicle, the driving experience database comprising the corresponding relation of the vehicle weight, the accelerator opening degree, the current vehicle speed and the target acceleration; judgingwhether torque compensation is needed or not according to the current acceleration and the target acceleration; and if torque compensation is needed, carrying out torque compensation. According to theinvention, torque compensation is carried out on the commercial vehicle based on the whole vehicle weight, the current vehicle speed and the current acceleration under the mountain road working condition, and the driving comfort and the driving safety are improved.

Description

technical field [0001] The present invention relates to the technical field of commercial vehicles, in particular to a control method, system, equipment and medium for driving commercial vehicles on mountain roads. Background technique [0002] With the rapid development of the economy and the gradual improvement of domestic road infrastructure, the logistics links in various places are getting closer and closer. Our country is a mountainous country, and a considerable number of logistics vehicles pass through the mountain roads between urban and rural areas and between cities every day. Compared with traditional multi-gear passenger vehicles, most new energy electric drive light commercial vehicles do not distinguish between driving modes, do not have a specific mountain road mode, and are generally much heavier than passenger cars, resulting in a loss of power when the truck enters the mountain road condition. Poor driving experience. When the vehicle is driven on a moun...
