Abstract
A stability control system (24) for an automotive vehicle as includes a plurality of sensors (28–37) sensing the dynamic conditions of the vehicle to determine imminent rollover. A controller (26) coupled to an active suspension (49) controls a restoring torque in response to the rollover signal by controlling the active suspension.
Claims22
A rollover control system for an automotive vehicle comprising:
- an active suspension having an independently adjustable unloading side and a an independently adjustable loading side;
- a rollover sensor generating a rollover signal in response to an imminent rollover of the vehicle;
- and
- a controller coupled to said rollover sensor for controlling the active suspension to generate a restoring torque in response to the rollover signal.
A method of controlling rollover stability of a vehicle having an active suspension having a first side suspension and a second side suspension comprising the steps of:
- sensing imminent rollover of the vehicle and generating a rollover signal in response thereto;
- generating a restoring torque in response to the rollover signal by controlling the active suspension.
A method of controlling rollover stability of a vehicle having a first side suspension and a second side suspension comprising the steps of:
- sensing imminent rollover of the vehicle and generating a rollover signal in response thereto;
- determining a loading side and an unloading side of the vehicle in response to the rollover signal;
- unloading the first side suspension corresponding to the unloading side suspension;
- loading the second side suspension corresponding to the loading side suspension;
- generating a restoring torque in response to the steps of unloading and loading to counter the imminent rollover.
