Problems solved by technology

However, the power battery pack used in the existing swappable pure electric heavy truck is not only very heavy but also installed in a high position. Although it is required in the instruction manual that sudden acceleration and deceleration should be avoided during driving, there is no guarantee that each The driver can execute according to the instruction manual; when the vehicle accelerates or decelerates sharply, the power battery pack will have the risk of leaning forward or backward, even if the device for fixing the power battery pack is equipped with a locking mechanism, the power cannot be eliminated. The risk caused by the abnormal movement of the battery pack greatly threatens the safety of people and vehicles

Abstract

The invention discloses a method for preventing abnormal movement of a battery pack. The method comprises the steps of acquiring the current state of a vehicle; when the current state is the running state, determining the state of the battery pack in the vehicle; if the state of the battery pack is a working state, acquiring and recording a vehicle parameter change rate; according to the vehicle parameter change rate and a preset parameter change threshold value, judging whether the vehicle speed or the brake stroke of the vehicle is limited or not; and if the judgment result is yes, carryingout limiting control on the vehicle speed or the brake stroke of the vehicle. According to the method and device for preventing abnormal movement of the battery pack, the vehicle and the medium, the vehicle speed acceleration, the throttle opening degree change rate and the brake opening degree change rate can be monitored in real time in the vehicle running process, the overlarge opening degree is actively limited to prevent the battery pack from inclining forwards or backwards, driving safety is guaranteed, and intelligence is good.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a method, device, vehicle and medium for preventing abnormal movement of a battery pack. Background technique [0002] With the adjustment of the transportation structure such as "road-to-rail", the demand for long-distance road transportation has begun to decline, but the demand for short-distance transportation is showing a significant increasing trend, and short-distance transportation is the main position of new energy heavy trucks. Among them, considering problems such as low operating efficiency, high purchase cost, and battery performance concerns, battery-swappable pure electric heavy-duty trucks that can solve the above problems have received more and more promotion. However, the power battery pack used in the existing swappable pure electric heavy truck is not only very heavy but also installed in a high position. Although it is required in the instruction manual...
