“…When referring to the lateral "Stability indexes", for instance, yaw rate and sideslip angle, we can find the same trends with the aforementioned safety indexes as demonstrated in Figures 9,10,17,and 18. The RMSEs for yaw rate and sideslip angle improve about 67.6%, 29.5%, and 90.4%, 26.7% with respect to pure braking and static allocation in highway impact as shown in Table 4.…”

“…These systems are proposed to prevent possible crashes or impacts and protect the drivers and passengers from injuries. A lot of vehicle dynamics control techniques are growing industrialised as mounted active safety systems [16], such as anti-lock braking system (ABS) [17], electronic stability control (ESC) [18], active front steering (AFS) [19], torque vectoring [20,21], active limited-slip differential [22] etc. These systems contribute a lot to decrease the fatalities and injuries in road accidents [23,24].…”

In terms of the possible secondary or multiple events accidents (MEA) after an initial vehicle to vehicle (V2V) impact, this research proposes an active safety & stability controller for independent-driven electric vehicles towards recovering the vehicle to safety states after an impact. The controller aims to regulate the course angle and lateral deviation that enforce the vehicle back to its original driving path. The upper-level controller is derived based on sliding mode technique. And the low-level controller aims to solve a convex quadratic allocation problem, which inherently incorporates fault-tolerance property. The independent in-wheel-motor (IWM) fault is very likely to happen under a real V2V impact and it contributes much to the driving safety & stability. Two typical real-endcollision scenarios under low-and high longitudinal velocities are designed to verify the proposed controller performance. The low-and high velocities collisions aim to simulate the urban and highway accidents, respectively. Compared to other control methods, i.e. pure braking and static allocation, the RMSEs of safety (lateral deviation, course angle) and stability indexes (yaw rate, sideslip angle) under proposed controller reduce significantly both in urban and highway accidents. Moreover, the controller performs robust enough against the impact-induced IWM fault. It further supports the effectiveness at dealing with the safety and stability of the ego vehicle after an initial impact and prevent possible MEA.

“…It is proven in many simulation and experimental works, the superiority of its performance compared to the standard PID control method in controlling various dynamical systems (Abdelmaksoud et al, 2021; Al-Mola et al, 2012a; Hewit and Burdess, 1981; Muniandy et al, 2015; Priyandoko et al, 2009; Varatharajoo et al, 2011). This strategy was used in ABS to control the optimum wheel slip value in order to prevent the wheel from being totally locked under adverse operating conditions (Gaurkar et al, 2022; Lutfi, 2005).…”

The anti-lock brake system (ABS) is an active safety device used in ground vehicles to increase the brake force between the tire and the road during panic braking. Due to the high non-linearity of the tire and road interaction plus uncertainties derived from vehicle dynamics, a standard proportional-integral-derivative (PID) controller is not deemed enough for the system to produce optimum performance. An active force control (AFC) based scheme is proposed to enhance the robustness of the system and reject undesirable disturbances. A P-type iterative learning algorithm (ILA) is implemented in the AFC loop to estimate the vital parameter continuously for force feedback compensation. In this paper, the control scheme to be known as PID-ILAFC was validated experimentally through its implementation on a test rig. A hardware-in-the-loop (HIL) test via LabVIEW was formulated with novel intelligent control schemes to execute the algorithm in real-time, thereby practically verifying the response of the ABS in the wake of parametric changes and varied operating and loading conditions. The PID-ILAFC controller is specifically designed to provide a proper slip ratio close to the reference value, a reduced stopping distance, and stability in vehicle movement during panic braking. The results clearly exhibit more robustness and superior performance of the AFC-based ABS in achieving the reduced stopping distance and good slip ratio in comparison to the PID and passive counterparts for a dry road condition setting.

“…On taking friction factors of straight roads with homogeneous surfaces, the ABS shows a reduction in the braking distance. It was observed that the reduction range in such situations was 7%-18% which was much better than wheels without ABS (Gaurkar et al, 2022). In another work, the hydraulic ABS system with an intelligent controller control braking was tried based on the real-time slip ratio of the wheels estimated from vehicle velocity.…”

Purpose The Purpose of this study is to prove the possibility of developing low cost mechanical anti – lock braking system (ABS) for the passenger’s safety. Design/methodology/approach The design methodology of the proposed newer mechanical ABS comprises of two units, namely, the braking unit and wheel lock prevention unit. The braking unit actuates the wheel stopping as and when the driver applies the brake, whereas the wheel lock prevention unit initiates wheel release to prevent locking and subsequent slip/skidding. The brake pedal with master cylinder assembly and double-arm cylinder forms the braking unit, brake pad cylinder, movable brake pad, solenoid valve and dynamo forms the wheel lock prevention unit. The dynamo coupled with the rotor energises/de-energises the solenoid values to direct airflow for applying brake and release it, which makes the system less energy-dependent. Findings The braking unit aids in vehicle stops, by locking the disc with the brake pad actuated by a double-arm cylinder. The dynamo energises the solenoid valve to activate the brake pad cylinder piston for applying the brake on the disc. Instantaneously, on applying the brake the dynamo de-energises the solenoid to divert the pneumatic flow for retracting the brake pad thereby minimizing the braking torque. The baking torque reduction revives the wheel rotating and prevents slip/skidding. Originality/value Mechanical ABS preventing wheel lock by torque reduction principle is a novel method that has not been evolved so far. The system was designed with repair/replacement of the parts and subcomponents to support higher affordability on safety grounds.
