Abstract:
An autonomous mode controller (61) that outputs an acceleration command (SAa), a braking command (SBa) and a torque command (Ta) is connected to a steering actuator (33) and a traveling drive unit (52). The steering actuator (33) generates combined torque (T1) based upon steering torque (Tm) from a steering handle (32) and the torque command (Ta), and controls a steering angle (¸) of a vehicle based upon the combined torque (T1). The traveling drive unit (52) selects a larger one of an acceleration command (SAm) by an accelerator pedal (50) and the acceleration command (SAa) as an acceleration command (SA), and selects a larger one of a braking command (SBm) by a brake pedal (51) and the acceleration command (SBa) as a braking command (SB). The traveling drive unit (52) controls a vehicle speed based upon the acceleration command (SA) and the braking command (SB).
Abstract:
A vehicle motion control device includes curve shape acquisition means 2 for acquiring a shape of a curve present in front of a currently traveling vehicle, vehicle position acquisition means 3 for acquiring a position of the vehicle, and vehicle motion control arithmetic means 4 for computing, on the basis of the shape of the curve and the position of the vehicle, a command value relating to longitudinal acceleration to be caused to the vehicle. During a time interval from before the vehicle reaches a near end of the curve, until the vehicle has approached the curve and traveled to a site having a constant or maximum curvature of the curve, the vehicle motion control arithmetic means 4 computes a plurality of different negative longitudinal acceleration command values. Thus, even under a state of no lateral motion being caused to the vehicle, the vehicle motion control device accelerates/decelerates the vehicle while improving a driver's feeling of slowdown.
Abstract:
A method and control unit determines a fuel efficient acceleration behavior of a motor vehicle for a predetermined road section. The determination of the acceleration behavior is based on a determined initial speed of the motor vehicle in a first position in the road section, and a determined target speed of the motor vehicle in a determined second position in the road section, the second position being separated from the first position by an acceleration distance. The first position is determined such that the acceleration distance is less than or equal to a maximal acceleration distance Sacc, the maximal acceleration distance Sacc being dynamically determined based on at least one first road condition for the road section and on at least one characteristic of the motor vehicle.

A vehicle control system configured to stabilize a behavior of a vehicle during turning by correcting a driving force or a braking force. The vehicle control system comprises a lateral acceleration detecting means detecting longitudinal acceleration acting in an axle direction of the vehicle Ve (step S102); and a driving/braking force correcting means determining a changing amount Fctrl and a changing rate DFctrl of the correction based on the lateral acceleration Gy in case the running vehicle Ve is turned.

Abstract:
An attitude controller eliminates a skid motion of a banked vehicle when travelling through a curve. The attitude controller includes a lateral acceleration sensor 34 configured to obtain lateral acceleration, as rightward or leftward accelerations, acting on a vehicle of a motorcycle 1; a bank angle detector 46 configured to detect a bank angle of the vehicle, and a longitudinal force controller 32 configured to decrease, independently of each of the wheels 8, 23, an absolute value of a longitudinal force as the sum of forward and backward forces acting on front and rear wheels 8 and 23 based on the obtained lateral acceleration and the detected bank angle. The lateral acceleration sensor 34 obtains the lateral acceleration. The bank angle detector 46 detects the bank angle of the vehicle. The longitudinal force controller 32 decreases, independently of each of the wheels, the absolute value of the longitudinal force as the sum of the forward and backward forces acting on each of the wheels in accordance with the lateral acceleration and the bank angle. This achieves attitude control.
