Embodiment Construction

[0028] image 3 A vehicle 100 such as a car or truck is shown having four wheels 101, two of which are located on the left and right sides of the vehicle's head. Similarly, the other two wheels are located on the left and right sides of the rear of the vehicle, as is typical in conventional car configurations. However, those skilled in the art will appreciate that a vehicle may have any number of wheels.

[0029] As described in detail below, an in-wheel electric motor is integrated within each wheel 101 . Although the present embodiment describes a vehicle having an in-wheel electric motor associated with each wheel 101 , only a subset of wheels 101 may have an associated in-wheel electric motor as understood by those skilled in the art. For example, for a four-wheeled vehicle, only the front two wheels may have an associated in-wheel electric motor, or only the rear two wheels, or only a single wheel may have an associated in-wheel electric motor. Although the present emb...

Abstract

A suspension control system for a vehicle having wheels (52) mounted to the vehicle by means of a suspension arrangement mounted to mounting points on a vehicle body, wherein an electric motor is arranged to apply torque to said wheels To drive a wheel, the suspension control system includes a controller configured to adjust torque applied to the wheel by the electric motor based on relative longitudinal movement of the wheel relative to a mounting point on the vehicle.

Description

technical field [0001] The present invention relates to suspension control systems, particularly for vehicles having wheels driven by electric motors. Background technique [0002] A vehicle's suspension system has two main functions, the first is to isolate the body, and thus the vehicle's occupants, from road inputs, and the second is to improve the vehicle's ride by reducing load variations between the wheels and the ground. [0003] The characteristics of a vehicle suspension system can be characterized by the vertical and longitudinal flexibility of the suspension system. [0004] The vertical flexibility of a vehicle suspension system is typically produced by spring damping systems that are tuned to provide a good compromise between passenger comfort and handling. The spring is selected to have a sprung mass resonant frequency between about 0.7 Hz and 2 Hz. Lower resonance frequencies induce motion sickness, while higher resonance frequencies reduce rejection of road...
