  • Patent number: 8352120
    Abstract: A system and method for stability control of a vehicle using GPS data. The system and method can receive GPS data and optionally vehicle operating data or signals and define one of a brake-based stability control subsystem and a torque management-based stability control subsystem as the dominant stability control system. Based on the stability control subsystem defined as the dominant stability control system, the system and method provide stability control for the vehicle. The system and method also defines the dominant stability control system based on weather data.
    Type: Grant

  • Patent number: 8340880
    Abstract: A system and method for controlling torque and/or speed of wheels of a vehicle. The system and method receive one or more vehicle operating signals. Based on the received vehicle operating signals, the system and method determine whether one or more of a vehicle's wheels require torque or speed modification. If it is determined that one or more of the vehicle's wheels requires torque or speed modification, the system and method modifies the torque to drive, or speed of, a wheel or wheels based on the received vehicle operating signals. The modification is automatic and/or independent for each wheel. Some or all wheels can be coupled to respective wheel hubs having incorporated therewith an engagement/disengagement mechanism. The system and method can control the engagement/disengagement mechanism to modify the torque at, or speed of, the associated wheel based on the received vehicle operating signal or signals.

  • Patent number: 8229639
    Abstract: A system and method for stability control of a vehicle. The system and method can receive current vehicle operating data or signals as well as data or a signal from a traction control subsystem. Based on the received current vehicle operating data or signals data or a signal from a traction control subsystem, the system and method define one of a brake-based stability control subsystem and a torque management-based stability control subsystem as the dominant stability control system. Based on the stability control subsystem defined as the dominant stability control system, the system and method provide stability control for the vehicle.
