Problems solved by technology

[0006] However, if the monitoring system cannot receive torque information related to one of the wheels, in order to prevent dangerous yaw induction, the monitoring system usually puts the drive system in a safe state by disabling the entire drive system, resulting in the disabling of the vehicle

Embodiment Construction

[0021] Embodiments of the invention are described for use in a control system for preventing the induction of dangerous yaw conditions in the event of a loss of communication between two electric motors independently driving transversely mounted wheel. The control system is for a vehicle having a first wheel arranged to be driven by a first motor and a second wheel arranged to be driven by a second motor, wherein the first wheel and the second wheel are located laterally on the vehicle with respect to each other . The control system includes a first controller associated with the first motor and a second controller associated with the second motor. In the event that the first controller is unable to receive power or torque information produced by the second motor, when the second motor is placed in the first motor configuration, the first controller estimates A first power value of the power of the second motor, and when the second motor is placed in the second motor configu...

Abstract

A control system for a vehicle having a first wheel arranged to be driven by a first electric motor and a second wheel arranged to be driven by a second electric motor, wherein the first wheel and thesecond wheel are transversely located on the vehicle relative to each other, the control system comprising a first controller associated with the first electric motor and a second controller associated with the second electric motor, wherein the first controller includes means for estimating a first power value for the power applied to the second wheel by the second electric motor when the secondelectric motor is placed in a first motor configuration and means for estimating a second power value for the power applied to the second wheel by the second electric motor when the second electric motor is placed in a second motor configuration, wherein upon the occurrence of a predetermined condition the first controller is arranged to determine a first power differential between the power being applied to the first wheel by the first electric motor and the first power value and a second power differential between the power being applied to the first wheel by the first electric motor and the second power value, wherein if the first controller determines that if either the first power differential or the second power differential is greater than a predetermined value the first controlleris arranged to adjust the torque generated by the first electric motor or if both the first power differential and the second power differential are less than a predetermined value the first controller is arranged to maintain the torque generated by the first electric motor.

Description

technical field [0001] The invention relates to a control system, especially for a vehicle. Background technique [0002] With the increased interest in environmentally friendly vehicles, perhaps not surprisingly, there has been a corresponding increase in interest in the use of electric vehicles. [0003] While most commercial electric vehicles utilize a central electric motor that drives two or more wheels, an alternative that is gaining popularity employs in-wheel electric motors, where individual electric motors are to drive the respective wheels of the vehicle, allowing the torque transfer to each wheel to be independently controlled. The fast response characteristics of the electric motors and the independent torque control of the vehicle wheels allow in-wheel electric motors to be used to improve vehicle stability to supplement or replace additional vehicle stability control mechanisms. For example, independent torque control of in-wheel electric motors can be used ...
