This paper proposes an approach for optimized control of vehicle actuators as far as wear of individual components is concerned. The system is intended to improve the performance of existing balancing and protection systems working on component level. Well-tested and commonly known optimization algorithms are integrated into the onboard software to handle mutual dependencies of wear of components by generating an optimal coordination strategy. A suitable system architecture facilitates safe operation of the system and reduction of computational load. The approach especially focuses on electric vehicles with functional actuator redundancy and several power-supply units. Proper operation of the algorithm is demonstrated based on a full electric experimental vehicle. Thereby, tire wear is balanced while equalizing usage of the traction batteries and temperature levels of the drive motors.
