“…However, due to the difficulty-to-measure feature and the nonlinearity of tire forces, the method of monitoring the tire workload used in those researches can be unsuitable for implementation in practical scenario. Then the tire slip penalty function method proposed in [13] is adopted in this paper. First, define the combined slip of an individual tire as:…”

“…The designed algorithm will be compared with three other control systems to validate the effectiveness and handling enhancement: (1) only anti-lock braking system (ABS) equipped system (marked as Base); (2) four-wheel independent brake controlled system (marked as 4IB); (3) an integrated chassis control system by means of front/rear traction control and four-wheel independent braking (marked as AWD-4IB) [13]. Vehicles equipped with the first three systems are both front wheel driven, just as the prototype vehicle.…”

“…Guo et al [12] investigated the trajectory tracking of autonomous vehicles using the integration of 4WD and ESC, which considered the highly coupling effects of the vehicle and tire dynamics, and used a back-stepping sliding mode controller to decide the desired longitudinal/lateral forces. Joa et al [13] presented an integrated chassis control of front/rear 4WD and differential ESC, to improve the performance in normal driving and limit handling combined, in which a tire dissipation energy (TDE) and tire longitudinal/lateral combined slip-based cost function was proposed to calculate the desired virtual control input. Her et al [14] proposed an integration of three chassis modules: front/rear 4WD, ESC and ARCS, in the paper the 4WD system can generate the desired longitudinal acceleration while ESC is used to produce the desired yaw motion in steering scenario and ARCS can help manage the vertical load of every tire, which can expand the friction circle of every tire to a larger scale to enhance the lateral handling.…”

This paper proposes a coordinated chassis control (CCC) utilizing four-wheel differential braking, electronically controlled real-time four-wheel drive (4WD) and active front steering (AFS), aiming to improve the driving performance and handling stability during cornering. First, the performance of the single system is tested; then the hierarchical-structure control algorithm is designed: a supervisory controller to monitor vehicle states and determine the desired yaw rate, upper-level controller to decide the desired longitudinal forces and the desired yaw moment based on the driver intention and the consideration of vehicle stability, and the control allocation layer to distribute the actual control inputs to the actuators applying an optimal control allocation algorithm. Simulations of moderate driving/aggressive deceleration scenarios and a comprehensive test on a handling road are conducted to validate the effectiveness of the proposed control algorithm. The results of the simulations suggest that the proposed algorithm can effectively improve the driving speed in limit cornering without losing lateral stability, and reduce the tire dissipation energy compared with other control algorithms such as the electronic stability control system, the four wheel independent brake system and an integrated chassis control system proposed in a previous research. INDEX TERMS Coordinated chassis control, tire dissipation energy, limit handling, vehicle dynamics.

“…Under normal driving cycles, the energy efficiency of the power system is improved by the torque distribution between the front and rear wheels. Literature [8] proposes a hierarchical control algorithm for the all-wheel drive system. The upper layer is composed of the supervision-expected motion tracking controller and the lower layer is composed of the optimized controller.…”

All-wheel drive is an important technical direction for the future development of pure electric vehicles. The difference in the efficiency distribution of the shaft motor caused by the optimal load matching and motor manufacturing process, the traditional torque average distribution strategy is not applicable to the torque distribution of the all-wheel drive power system. Aiming at the above problems, this paper takes the energy efficiency of power system as the optimization goal, proposes a dynamic allocation method to realize the torque distribution of electric vehicle all-wheel drive power system, and analyzes and verifies the adaptability of this optimization algorithm in different urban passenger vehicle working cycles. The simulation results show that, compared with the torque average distribution method, the proposed method can effectively solve the problem that the difference of the efficiency distribution of the two shaft motors in the power system affects the energy consumption of the power system. The energy consumption rate of the proposed method is reduced by 5.96% and 5.69%, respectively, compared with the average distribution method under the China urban passenger driving cycle and the Harbin urban passenger driving cycle.
