Abstract:

A new modeling method for the variable ratio gear of the rack and pinion variable ratio steering gear was proposed in this paper. It was based on the characteristic that variable ratio gear pair meshing tooth profile surface are the envelope surface of each other and established a variable ratio gear three-dimensional model by simulating the gear machining process in CATIA and using Boolean subtraction operation. According to the related test standard of the variable ratio steering gear transmission ratio, a test bench was design and build, and the correctness of this modeling method was verif

Abstract:

For the TFC35 steer-by-wire forklift, a linear 3-degree-of-freedom forklift model is given, which provides a verification model for variable steering ratio design. The concept of ideal steering ratio is expounded. The variable steering ratio algorithm based on constant yaw rate gain and the variable steering ratio algorithm based on constant lateral acceleration gain are studied. A variable steering ratio algorithm based on two kinds of gain combination is proposed. The advantages and disadvantages of the above three static variable steering ratio algorithms based on constant gain are simulate

Abstract:

To improve vehicle handling performance, a variable steering ratio characteristic for steer-by-wire system is designed. The steering ratio is adjusted by a compensating coefficient according to vehicle longitudinal speed and steering wheel angle. To evaluate the performance of vehicle with variable steering ratio, simulations are conducted based on an objective evaluation index, which consists of quadratic cost functions of vehicle lateral deviation, steering angular speed, vehicle lateral acceleration and roll angle. By using the optimized data from the simulation results, a Takagi-Sugeno fuz

Abstract:

This article presents the geometric and functional characteristics of a steering gearbox with variable transmission ratio, which contains a translating wheel (circular curved rack) in gearing with an eccentric sector (segment). The solution requires no special technology because it uses conventional involute gears, being obtained/derived from a classic gearbox with constant ratio by changing the gearing characteristics. The precision of the steering system and the reversibility of the gearing are not affected by these modifications, the driver having a good/safe control of the vehicle. This ge

Abstract:

In conventional steering system, during the parking maneuver, driver required large turned on the steering wheel to move the fornt tyre. Thus, it will increase the driver burden when turned the steering wheel. The feature of variable steering ratio (VSR), help to reduce driver burden. Moreover, it improves the vehicle maneuver at lower and high speed. This paper, proposed a control algorithm of variable steering ratio (VSR) in vehicle SBW system. The concept of hyperbolic tangent is used where it not only improved the maneuverability at lower speed, but also reduces the driver burden on the st

In order to obtain the ideal steering performance, an active rear wheel steering (ARS) controller, based on the variable transmission ratio control strategy, is developed in this paper. ARS controller using sliding mode technique is designed to follow the desired yaw rate which is calculated by the ideal variable transmission ratio. Simulation result shows that, the proposed control strategy both obtains desired steering performance and provides the obvious benefits for the human driver.

The main purposes of the variable-gear-ratio steering system are to connect the steering wheel and the front-wheel steering mechanism and to coordinate the turning angle of the front wheels, according to the steering-wheel angle and the speed of the vehicle, in order to maintain a constant “desired yaw rate gain” at a constant speed of vehicle. However, the value of the desired yaw rate gain should be varied at different vehicle speed to give better maneuv

Abstract:

The steering arrangement of a 6x6 off-road military vehicle was investigated, with the aim to determine if a variable steering ratio between the first and second steering axle of the vehicle will make an improvement in the steady and transient state handling of the vehicle. Low speed manoeuvring was evaluated, comparing the vehicle steering geometry with Ackerman geometry. For steady state handling, a bicycle model was developed, and constant radius simulations at various track radii, vehicle speeds and steering ratios (ratio between the first and second steering axle) was performed.

Abstract:

Variable-gear-ratio steering is an advanced feature in automotive vehicles. As the name suggest, it changes the steering gear ratio depending on the speed of the vehicle. This feature can simplify steering for the driver, which leads to various advantages, such as improved vehicle comfort, stability, and safety. One serious problem, however, is that the variable-gear-ratio system generates unnatural torque to the driver whenever the variable-gear-ratio control is activated. Such unnatural torque includes both low-frequency and steering-speed-dependent components. This paper proposes a control

Abstract:

This paper has studied the variable steering ratio for steering-by-wire (SBW) based on the 29 DOF vehicle dynamic model, which kept the steering gain of vehicle constant. And the steering ratio varied with the vehicle velocity and hand wheel angles. We have proposed three control strategies for SBW including front wheel control, yaw rate feedback control and yaw rate & acceleration feedback control. We compared these three control methods by simulation and simulator tests. We have researched the forward and feedback control methods in the four wheels (4WS) for SBW system. And compared with
