Abstract

The invention discloses a method for adjusting suspension system parameters based on road conditions, which is executed by a vehicle-mounted computer and comprises the steps of receiving first indication information sent by a first road side device, responding to the received and analyzed first indication information, providing first reminding information for a driver, continuously monitoring whether the driver reduces the speed of a vehicle and turns on a high beam of the vehicle, determining whether to analyze second indication information sent by a second road side device based on a monitoring result, acquiring an image in front of the vehicle after the high beam of the vehicle is turned on, and adjusting the suspension system parameters based on characteristics of obstacles in the image in front of the vehicle. The self-adaptive suspension system effectively solves the problem that the self-adaptive suspension system cannot pre-judge in advance and respond to road surface impact due to limited sensing of the sensor of the vehicle under the low-visibility environment.

Description

Road condition-based suspension system parameter adjusting method and system Technical Field The invention relates to the technical field of electric automobiles, in particular to a method and a system for adjusting suspension system parameters based on road conditions. Background The electric automobile suspension system is specially optimized and developed from the adaptation of the traditional internal combustion engine model to the characteristic of an electric drive system. The suspension system can effectively realize bidirectional vibration isolation, namely, the impact of road impact on key components such as a motor, a battery pack and the like is isolated, and the transmission of the vibration of the motor to a vehicle body is restrained, so that the durability and the safety of a driving system and a battery are comprehensively protected. However, fixed parameter suspension systems have difficulty achieving optimal vibration isolation under all conditions. Therefore, the self-adaptive adjusting technology of the suspension system is developed, the state and road conditions of the vehicle are monitored in real time through the sensor, and the suspension rigidity or damping is actively adjusted, so that the vibration protection of the motor and the battery pack is dynamically optimized under various driving scenes, and the NVH performance and the part reliability of the whole vehicle are improved. However, in low visibility environments (such as at night), existing adaptive adjustment techniques may result in insufficient damping of the suspension system due to their inability to function fully, thereby increasing the risk of accidental damage to the motor or battery. Disclosure of Invention In order to achieve the above purpose, the invention provides a method and a system for adjusting suspension system parameters based on road conditions.
