“…There are two drive-only topologies, which feature either an allwheel drive topology [106,107] or the wheel-individual all-wheel drive topology mentioned above. A brake-only topology using wheel-individual brakes at all wheels is encountered as well [64,72,92,122,143,147,178,185,188,200]. For these topologies, steering angles act as system parameters or as disturbance if a steering actuators are mentioned but not actively used, cf.…”

“…Lateral vehicle dynamics -i. e., yaw and lateral motionare the second most encountered control target in the surveyed literature. They are considered in 48 publications addressing actuator degradations [34, 38, 46, 49, 57, 59, 61, 62, 65-68, 71, 72, 76, 80, 81, 87, 89, 93, 95, 96, 99, 100, 108, 111-116, 119-122, 132-134, 147-149, 155, 159-161, 164, 165, 171] and six addressing tire blowouts [178,183,[185][186][187][188]. In contrast, the reviewed approaches seldom target pure longitudinal dynamics [45,106,107,123,124,143].…”

The advent of automated vehicles operating at SAE levels 4 and 5 poses high fault tolerance demands for all functions contributing to the driving task. At the actuator level, fault-tolerant vehicle motion control, which exploits functional redundancies among the actuators, is one means to achieve the required degree of fault tolerance. Therefore, we give a comprehensive overview of the state of the art in actuator fault-tolerant vehicle motion control with a focus on drive, brake, and steering degradations, as well as tire blowouts. This review shows that actuator fault-tolerant vehicle motion is a widely studied field; yet, the presented approaches differ with respect to many aspects. To provide a starting point for future research, we survey the employed actuator topologies, the tolerated degradations, the presented control approaches, as well as the experiments conducted for validation. Overall, and despite the large number of different approaches, the covered literature reveals the potential of increasing fault tolerance by fault-tolerant vehicle motion control. Thus, besides developing novel approaches or demonstrating real-time applicability, future research should aim at investigating limitations and enabling comparison of fault-tolerant motion control approaches in order to allow for a thorough safety argumentation.

“…A coordinated control approach based on active front steering and differential braking was then proposed, showing better performance compared with a steering approach alone. 23 An assumption has been established during this research that the vehicle speed changes so little that it can be regarded as a constant. Generally, the driver may decelerate the vehicle after a tire blow-out, and the time-varying speed markedly affects the vehicle dynamics, so it is significant to take the speed change into account.…”

This paper presents a robust control approach to keeping directional and driving stability for a road vehicle after a tire blow-out. Considering the time-varying vehicle velocity as well as the uncertain tire characteristics, a linear parameter varying vehicle model is built. With front wheel steering angle and yaw control moment as control inputs, a gain-scheduling H∞ controller is developed to attenuate the effects of a flat tire. An optimal control allocation law is presented to perform the yaw control moment by differential braking on the other three tires. Finally, a hardware-in-the-loop testing system, composed of the veDYNA high-fidelity software program and an actual automotive hydraulic braking system, is utilized for controller validation. The results clearly demonstrate the effectiveness of the proposed coordinated controller in improving vehicle directional stability and robustness against the disturbances caused by a tire blow-out.

“…Pohl et al [5] stated that a puncture of the tires in motion can lead serious accidents and imperil human life. For this reason, active braking and steering systems are designed to compensate the vehicle stability during sudden decreases in tire pressure [6,7]. Moreover, it leads the fuel consumption and exhaust emissions to increase.…”

This study aims to experimentally investigate accordance between tire pressure and vertical deflection of tire in order to use in TPMS (Tire Pressure Monitoring System). For this aim, the resonance frequency of vertical deflection of tire is determined by using test results. Thus, the road tests have been conducted on dry flat road for measuring the tire deflection. These tests are run at constant vehicle speeds 30 and 100km/h for tire pressures 15, 20, 25, 30, 35psi. Therefore, the vertical deflection changes have been measured under same road conditions with different vehicle speeds. The frequency responses of the measured vertical deflections are obtained by implementing sampled root mean square (SRMS) method to vertical deflection signals. The resonance frequency of the vertical deflection is taken from the frequency responses. The results show that the accordance between tire pressure and vertical deflection of tire is achieved irrespective of the changes in vehicle speed. Consequently, the algorithm to detect the drops in tire pressure is developed by using the time and frequency domain results.
