This research focuses on four-wheel-drive electric vehicles. On the basis of hierarchical coordinated control strategy, system driving force distribution regulation and differential braking was designed to increase vehicles steering stability under special road working conditions. A seven-degree-of-freedom model an vehicle established in MATLAB/Simulink, then a coordination Electronic program d...

The loader has a lot of recoverable braking energy due to its larger mass and frequent starts/stops. For 5-ton pure electric drive loader, an emergency intention recognition strategy based on hydraulic pressure was proposed. acceleration pedal brake used distinguish different intentions, the system as feedback parameter for improve safety. Aiming at electro-hydraulic composite mode switching, c...

Based on the structural features of electric vehicle (EV) driven by in-wheel motors and the characteristics of low speed as well as high torque for in-wheel motors, regenerative braking method for in-wheel motors has been presented. All braking torque for vehicle deceleration is output by in-wheel motors under Medium-intensity braking condition for the sake of recovering the maximum braking ene...

1. The aim of this study was to investigate the role of the antagonist muscle in determining the accuracy of fast, single-joint motor responses to a target. We recently found that C5/C6 tetraplegic subjects, who lacked voluntary control of their triceps muscle, were less accurate than control subjects in producing fast flexion movements to a target. 2. Two hypotheses are proposed to account for...

Wheel force transducer (WFT), which measures the three-axis forces and three-axis torques applied to the wheel, is an important instrument in the vehicle testing field and has been extremely promoted by researchers with great interests. The transducer, however, is typically mounted on the wheel of a moving vehicle, especially on a high speed car, when abruptly accelerating or braking, the mass/...

OBJECTIVE To characterize biomechanical differences in gait between dogs with and without an amputated thoracic limb. ANIMALS Client-owned dogs (16 thoracic-limb amputee and 24 quadruped [control] dogs). PROCEDURES Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance phase. RESULTS Amputees had significant i...

An effective and reliable fast braking system for three-phase induction motor designed with the combinations of two or more conventional braking methods are discussed in this paper. A series of experiments were conducted in order to find out the speed range at which the most effective and efficient braking occurs corresponding to each conventional braking method and also to determine the minimu...

Nowadays, better driving also means better braking. To this end, vehicle designers must find all failures during the design phase of antilock braking systems which play an important role in automobiles safety. However, mechatronic systems are so complex and failures can be badly identified. So it is necessary to propose a design approach of an antilock braking system which will be able to avoid...
