ENHANCED VEHICLE STABILITY
An assembly includes a leadscrew defining a central axis, a strut movable along the leadscrew upon rotation of the leadscrew, a camber angle of a wheel changeable according to movement of the strut along the leadscrew, and a motor drivably connected to the leadscrew, the motor defining a motor axis, wherein the central axis of the leadscrew is transverse to the motor axis.
VEHICLE CONTROL SYSTEM AND METHOD
Embodiments of the present invention provide a control system (100) for determining a suspension calibration of a vehicle (800). The control system (100) has one or more controllers (120) that receive route data indicative of a route ahead of the vehicle (800). One or more processors (130) determine, from the route data, a prediction of a first acceleration at a first location (320) ahead of the vehicle (800) and a second acceleration at a second location (330) ahead of the first location(320). The one or more processors (130) determine a suspension calibration of the vehicle (800) in dependence on the second acceleration. The actual acceleration of the vehicle (800) is measured at the first location (320) and compared with the first acceleration. If the measured and first acceleration are within a predetermined tolerance, the processor (120) produces a suspension control signal at output (121) which is received by a suspension controller (140) to apply the suspension calibration prior to the vehicle (800) arriving at the second location (330).
METHOD OF CONTROLLING VEHICLE WHEN VEHICLE PASSES OVER SPEED BUMP
A method of controlling a vehicle when the vehicle passes over a speed bump, may include: dividing sections of the road into a first section within a first time period before the front wheel of the vehicle collides with the speed bump, a second section while the front wheel collides with the speed bump, a third section within a second time period before the rear wheel collides with the speed bump, and a fourth section while the rear wheel collides with the speed bump; and controlling and distributing at least one of suspension damping force, driving power and braking force to the front wheel and the rear wheel for each of the first section, the second section, the third section and the fourth section to reduce the amount of impact to be applied when the vehicle collides with the speed bump and to reduce a vertical motion of the vehicle that occurs while the vehicle goes over the speed bump.
Electrically powered suspension system
An electrically powered suspension system includes: an electromagnetic actuator; an information acquisition unit configured to acquire time-series information related to stroke position of the electromagnetic actuator, information on stroke velocity, and an amount of change in stroke of the electromagnetic actuator and information on a stroke direction based on the time-series information; a damping force calculation unit configured to calculate target damping force based on the information on the stroke velocity; and a drive control unit configured to control driving of the electromagnetic actuator using target driving force obtained based on the target damping force. The damping force calculation unit calculates equivalent friction compensation force based on the amount of change in the stroke and the information on the stroke direction, and corrects the target damping force based on the calculated equivalent friction compensation force. The equivalent friction compensation force has elastic force component and dynamic friction force component.

Aspects and implementations of the present disclosure relate to performance and safety improvements for autonomous trucking systems, including techniques of obtaining an identification of an unfavorable condition on a route of an autonomous vehicle (AV), causing the AV to exit the route, and performing one or more waiting loops until the unfavorable condition is resolved, the AV is rerouted, assistance arrives, and the like.
SUSPENSION CONTROL APPARATUS
A suspension control apparatus includes: a variable damper; a communication unit provided inside a vehicle to receive a dynamic map from a cloud; and a controller configured to adjust a force generated by the variable damper. The controller includes: a state estimation unit, which is provided inside the vehicle, and is configured to detect a motion of the vehicle; an operation-stability controller configured to calculate an A.sub.FB command value for the variable damper based on internal information output from the state estimation unit; and a dynamic-map controller configured to calculate an FF command value for the variable damper based on the dynamic map received from the communication unit. The controller determines a command value for the variable damper from the A.sub.FB command value and the FF command value.
