1. Introduction Typical vehicle models for 4WS (four wheel steering) are composed of steering as well as roll motion, drive train and tyre dynamics. Some models for vehicles are modelled along the 2 DOF (degrees of freedom) bicycle model but such models fail to compensate for roll angle modelling and only relate lateral acceleration and yaw rates…

Introduction

The vehicle is symmetrical about the x-z axis; 2. The vehicle’s total mass  is lumped; 3. The vehicle’s roll axis is fixed and ; 4. The road’s surface conditions are consistent throughout the modelling; 5. Small angle approximations apply to the vehicle’s motion. The dynamics of the 4WS vehicle system can be divided broadly into three categories which are: 1. Tyre side forces; 2. Yaw moments; 3. Roll moments. These aspects of the steering system will be investigated separately based on three kinds of steering systems which are the 2WS (two wheel steering) with front wheel steering, 4WS under 40 km/h where the wheels are steered in opposite phases and 4WS over 40 km/h where the wheels are steered in the same phase. The three modes of steering and the relevant dynamics and motion investigation are discussed below. 2. Vehicle Dynamics Where: The variables ,  and  all represent various kinds of disturbances that may affect the lateral, yaw and roll directions such as drag effects, side wind gusts, braking on ice, modelling uncertainties, loads, a flat tyre, an uneven road etc. These external disturbances may exert a sizeable influence in certain circumstances but for the sake of this investigation these disturbances will be neglected. ...

Vehicle Steering Wheel Heart Rate Monitor
The system would be configured to contact emergency medical services providing the location of the patient and it can apply brakes to vehicle to prevent an accident. This system will require the following components for its successful implementation. The first one is a device that reads the driver’s heart rate from the grip of the steering wheel. These devices function by either counting pulses…

Wheel Nut with Mechanical Locking/Unlocking Device
The two features demand that the nut have particular strength features and endurance to prevent unprecedented detachment. Additionally, the nut must have a secure locking and unlocking mechanism to enable the replacement of the wheel in case of damage. The design of the nut consequently influences the design of the wheel to ensure compatibility thus efficiency. The design of the two relies on the…
