Magnetic Coil

Most solenoid valves in use today require a magnetic coil to be continuously energized to maintain the magnetization of the magnetic body in order to operate. The problem is that if the power is still supplied, the power consumption will continue. In addition, problems such as shortening the lifespan of solenoid valve internal parts due to the increase in the internal temperature of the electronic stability control (ESC) due to the continuous heating of the magnetic coil, and malfunction due to instantaneous power failure may occur. In this study, we conducted a study on the permanent magnet traction control valve (TCV) for ESC that can minimize the unnecessary power consumption of electric vehicle batteries. For optimal permanent magnet design, polarity direction setting and permanent magnet specifications were studied through FE simulation. A permanent magnet TCV was fabricated and an electromagnetic force test was conducted to compare and evaluate it with the FE simulation result. By using a permanent magnet, it was possible to lower the initial current value for the TCV to drive, therefore, it was possible to develop a permanent magnet TCV that can minimize the unnecessary power consumption of electric vehicle batteries.

Rollover Stability

This paper provides a brief description of a Rollover Stability Mechanism in modern day cars incorporating the use of a modified suspension system which enables us to stop unexpected vehicle rollovers while they take place. Rollover mechanisms in conventional cars are incorporated with the help of anti roll bars which helps in stabilizing the car. Modern day cars are incorporated with user controlled programmes which would automatically control the car before the rollover takes place. The ESC (Electronic Stability Control) is one of those programmes which uses both ABS (Anti Brake Locking System) and TCS (Traction Control System) systems. This system identifies the various prerequisites that take place before a rollover and takes appropriate measures to avoid the forthcoming rollover. Inspite of this we see a lot of accidents due to over speeding ultimately leading to rollover at the turns or skidding of the car in tight turns at high speeds. This paper focuses on a method which can be used as a secondary safety measure for rollover accidents. The system discussed in this paper elaborates the use of a modified suspension system which is incorporated with the modern day ESC (Electronic Stability Control) unit in the vehicle. The Suspension used here is a hydraulic suspension system which is literally a piston cylinder arrangement with an inlet and outlet port for the hydraulic fluid.

An electronic stability control (ESC) based on torque distribution is proposed for an eight in-wheel motor-independent drive electric vehicle (8WIDEV). The proposed ESC is extremely suitable for the independent driving vehicle to enhance its handling stability performance. The vehicle model is established based on a prototype 8WIDEV. A hierarchical control strategy, which includes a reference state generation controller, an upper-level vehicle controller, and a lower-level optimal control allocation controller, is utilized in the ESC. The reference state generation controller is used to obtain the ideal reference vehicle state. The upper-level vehicle controller is structured based on sliding mode control, which obtains the generalized objective force during 8WIDEV movement, therein considering the side slip angle and yaw rate. The lower-level optimal control allocation controller attempts to allocate the vehicle’s objective force in each motor optimally and reasonably. The model is validated by field measurement results under the step input condition and snake input condition. Simulation results from a hardware-in-the-loop (HIL) simulation platform indicate that the ESC based on the optimized allocation proposed for 8WIDEV achieves better stability performance compared with direct yaw moment control (DYC).
