7 Jun 1996TL;DR: In this paper, a vehicle attitude control device including a yaw moment control mechanism and a controller is provided for controlling the yaw rate in a normal target follow-up control mode.
Abstract: A vehicle attitude control device including a yaw moment control mechanism (26) for giving a yaw moment to the vehicle and controlling the yaw moment, and a controller (30) for controlling the yaw moment control mechanism in a normal target follow-up control mode so that the actual yaw rate detected by a yaw rate sensor (44) coincides with a target value determined on the basis of an angle of rotation of a steering wheel (10) detected by a steering wheel angle sensor (40), and wherein a yaw moment reducing device (30, 40, 44) is provided for reducing the yaw moment to be given to the vehicle by the yaw moment control mechanism, to a reduced value smaller than a normal value to which the yaw moment is controlled in the normal target follow-up control mode. The yaw moment reducing device is operated in at least a second phase of a countersteering period following a first phase which is initiated by vehicle operator's countersteering manipulation of the steering wheel (10) upon slipping of rear wheels (22) of the vehicle during vehicle turning outwardly of the turning direction so as to countersteer the vehicle.

TL;DR: In this article, the authors proposed a safety device for motorcycle driving to prevent the motorcycle from being overturned by correctly detecting a lateral G, one of the motorcycle behavior elements, which varies during driving, by allowing the front and rear brakes to operate regardless of the rider's intention when a motorcycle behavior is unstable and determined that risk of overturn is high, thus leading to the stability of the behavior.
Abstract: PROBLEM TO BE SOLVED: To provide a safety device for motorcycle driving to prevent the motorcycle from being overturned by correctly detecting a lateral G, one of the motorcycle behavior elements, which varies during driving, by allowing the front and rear brakes to operate regardless of the rider's intention when a motorcycle behavior is unstable and determined that risk of overturn is high, thus leading to the stability of the behavior. SOLUTION: The safety device for motorcycle driving derives conditions for determining a motorcycle behavior from a gyro-sensor and a lateral G sensor built in a hybrid sensor 20, and distributes brake forces to the front and rear wheels in accordance with the motorcycle behavior so that a variation of motorcycle's rolling always falls within a range of the rider's control, and then the brake control assistance to transit the behavior from an unstable state to a stable state is automatically provided by the system on behalf of the rider.

29 Jun 1990TL;DR: In this paper, a riding simulation system of motorcycles provides at least a model motorcycle on which a person can ride and which can be operated by a person, in response to the operation and movement of the person who rides on the model motorcycle, the model motorcycles is moved by a movable mechanism in a desirable direction such as a yawing direction, a rolling direction and a pitching direction.
Abstract: A riding simulation system of motorcycle provides at least a model motorcycle (13) on which a person can ride and which can be operated by a person. In response to the operation and movement of the person who rides on the model motorcycle, the model motorcycle is moved by a movable mechanism in a desirable direction such as a yawing direction, a rolling direction and a pitching direction. Preferably, the moving image such as the scenery which is seen from the running motorcycle is displayed in front of the person who rides on the model motorcycle. Such moving image is varied in response to the driving condition of the model motorcycle.

TL;DR: In this paper, the authors proposed a follow-up travel control scheme for a single-vehicle scenario where the following vehicle is assumed to be a single motorcyclist and the second preceding vehicle is a single vehicle.
Abstract: PROBLEM TO BE SOLVED: To execute optimum follow-up travel control depending on a travel status even if a follow-up target is a motorcycle and the motorcycle is in a travel status wherein it tries to pass the second preceding vehicle ahead. SOLUTION: While a motorcycle as the preceding vehicle of an associated vehicle 1 is set as a follow-up target, a movement of the motorcycle in a width direction is detected, and if the second preceding vehicle traveling ahead of the motorcycle is detected, acceleration of the associated vehicle 1 is suppressed at acceleration of the motorcycle as the follow-up target. While the motorcycle and the second preceding vehicle travel side by side, they are accurately separately recognized from width information and a motorcycle movement direction put in memory in the preceding condition, and the follow-up target of follow-up control is shifted to the second preceding vehicle in follow-up control.

8 Apr 2002TL;DR: In this article, an electric steering controller is used for countersteering on a so-called μ split road surface in an electric vehicle, where the steering torque for a steering wheel is controlled in accordance with steering operation.
Abstract: PROBLEM TO BE SOLVED: To easily perform countersteering operation when giving braking force on a so-called μ split road surface in an electric steering controller. SOLUTION: In a steering torque control block B0, steering torque for a steered wheel of a vehicle is controlled in accordance with steering operation. Moreover, in a braking force inference block B1, braking force given to each wheel of the vehicle is inferred to infer a difference in braking force given to right and left wheels in a right and left braking force difference inference block B2 based on the braking force inferred in the block B1. Assist steering torque is given to the steering torque control block B0 by an assist steering torque giving block B3 in accordance with a difference in braking force on the right and left wheels to assist operation when performing countersteering.
