VEHICLE CONTROL DEVICE, VEHICLE CONTROL METHOD, AND VEHICLE CONTROL SYSTEM
An electrically controlled differential gear is disposed between a right front wheel and a left front wheel of a vehicle. The electrically controlled differential gear includes a clutch mechanism that limits a differential operation of the electrically controlled differential gear. A second ECU (control portion) obtains information as to failure associated with actuation of a right front electric brake mechanism. The second ECU obtains a physical amount relating to a required braking force which is applied to the left front wheel and the right front wheel. The second ECU outputs a differential limiting control command for limiting the differential operation of the electrically controlled differential gear to the clutch mechanism (or more specifically, a differential ECU that controls the clutch mechanism) based on the information as to the failure and the physical amount relating to the required braking force.
AUTOMATIC VEHICLE SPEED CONTROL SYSTEM
An automatic vehicle speed control system for use in a vehicle having an implement is disclosed. The automatic vehicle speed control system includes: a controller configured to: set a speed of the vehicle to a creep setting; monitor one or more operating conditions of the implement; and automatically adjust the speed of the vehicle based on the one or more operating conditions of the implement.
Systems and Methods for Compensating for Steering System Failure
An electric vehicle controls turning of the electric vehicle in accordance with the orientation of the wheels and skid steering to match the path and turning radius as indicated by the steering wheel. A processing circuit detects the position of the steering wheel and determines the direction of the turn and the resulting path and turning radius of the electric vehicle. The processing circuit either measures the orientation of the wheels or captures data regarding the turning radius of the electric vehicle. The processing circuit controls the traction motors of the electric vehicle so that the actual path and turning radius of the electric vehicle matches the path and turning radius indicated by the steering wheel. Further, the processing circuit may further control controls the traction motors to attempted to maintain the speed of the electric vehicle as indicated by the throttle.
BEHAVIOR PLANNING FOR AUTONOMOUS VEHICLES IN YIELD SCENARIOS
In various examples, a yield scenario may be identified for a first vehicle. A wait element is received that encodes a first path for the first vehicle to traverse a yield area and a second path for a second vehicle to traverse the yield area. The first path is employed to determine a first trajectory in the yield area for the first vehicle based at least on a first location of the first vehicle at a time and the second path is employed to determine a second trajectory in the yield area for the second vehicle based at least on a second location of the second vehicle at the time. To operate the first vehicle in accordance with a wait state, it may be determined whether there is a conflict between the first trajectory and the second trajectory, where the wait state defines a yielding behavior for the first vehicle.
TRACTION CONTROL METHOD AND TRACTION CONTROL APPARATUS FOR VEHICLE
A traction control method and a traction control apparatus for a vehicle are provided. The traction control method includes: estimating driving torque for each wheel and a difference between left and right wheel rotation speeds; determining a situation, in which the difference between the left and right wheel rotation speeds exceeds a first set value, to be a split wheel spin situation; estimating a maximum coefficient of friction between a spinning wheel and a road surface in the split wheel spin situation and estimating a maximum driving torque, at which the road surface is acceptable, by the maximum coefficient of friction; and obtaining a difference between driving torque of the spinning wheel and the maximum driving torque to calculate a road surface limitation excess driving torque and determining entry into traction control when the road surface limitation excess driving torque exceeds a second set value.
