Problems solved by technology

[0003] At present, the calculation of slope information for slope road conditions is mainly through the vehicle dynamics estimation method to calculate the vehicle driving force, driving resistance and rolling resistance, etc., and then calculate the slope resistance, and then calculate the slope value according to the slope resistance; or according to the acceleration sensor The value and the acceleration value in the direction of the vehicle body form an angle to obtain the slope value, but these two methods cannot accurately calculate the actual slope value of the current vehicle in the slope condition, which leads to the shift strategy when the vehicle is in the slope condition. Not accurate enough, affecting driving experience

Abstract

The invention discloses a speed change method and device applied to a vehicle, electronic equipment and a storage medium, and the method comprises the steps: determining the target working condition information of a target vehicle, and determining a target data processing mode corresponding to the target working condition information; determining target pitch angle information of the target vehicle based on the target data processing mode; according to the target pitch angle information, target gear information corresponding to the target vehicle is determined, and the target vehicle is driven to run based on the target gear information. The problem that the target vehicle gear information is determined only according to the ground gradient information, but the pitch angle information of the vehicle is ignored, so that the gear information is inaccurate during vehicle gear shifting is solved, and the effects that more accurate gear information is provided for the vehicle during vehicle gear shifting, and then the vehicle speed is adjusted based on the gear information are achieved.
