Abstract
A method of controlling stability of a motorized vehicle having an electric motor as a drive source includes determining a slope of a road ahead, when sensing a sudden slope change point as a result of determination, determining a correction section based on the sudden slope change point, and correcting stability control torque in the correction section to compensate for motion of the vehicle body due to a change in the slope of the road using a pitching motion of the vehicle body caused by the torque of the electric motor.
Claims19
A method of controlling stability of a motorized vehicle having an electric motor as a drive source, the method comprising:
- determining a slope of a road ahead;
- when sensing a sudden slope change point as a result of determination, determining a correction section based on the sudden slope change point;
- and
- correcting a stability control torque in the correction section to compensate for motion of a vehicle body due to a change in the slope of the road using a pitching motion of the vehicle body caused by a torque of the electric motor.
A non-transitory computer-readable recoding medium having a program recorded thereon, the program to direct a processor to perform acts of:
- determining a slope of a road ahead;
- when sensing a sudden slope change point as a result of determination, determining a correction section based on the sudden slope change point;
- and
- correcting a stability control torque in the correction section to compensate for motion of a vehicle body due to a change in the slope of the road using a pitching motion of the vehicle body caused by a torque of the electric motor.
A motorized vehicle comprising:
- an electric motor;
- a first controller configured to control the electric motor;
- and
- a second controller configured to:
- determine a slope of a road ahead;
- when it is determined that a sudden slope change point is sensed, determine a correction section based on the sudden slope change point;
- correct a stability control torque in the correction section to compensate for motion of a vehicle body due to a change in the slope of the road using a pitching motion of the vehicle body caused by a torque of the electric motor;
- and
- transmit, to the first controller, a torque command to which the corrected stability control torque is applied.
