Electric vehicle load leveling systems and methods

Abstract

An electric vehicle may be equipped with an adaptive suspension system that includes a chassis, a suspension system coupled to the chassis, and at least one helper spring configured to assist the suspension system. The vehicle may include at least one sensor configured to measure suspension travel, including vertical displacement between the vehicle's wheels and body. A controller, coupled to the helper spring and the sensor, may adjust the stiffness of the helper spring based on the measured travel. The stiffness of the helper spring may be varied in response to changes in load, such as added or removed weight, to improve ride quality, stability, and handling. The system may further include multiple helper springs, a user interface for manual adjustment, and an automatic adjustment feature based on the suspension's measured travel.
