Abstract:
The present invention relates to a method for calculating a driver's desired yaw rate of a vehicle (100) for use in a vehicle movement control system (220), comprising the steps of, determining the current yaw rate of the vehicle, determining the rate of the vehicle's steering wheel (110) rotation. The method further comprises the steps of calculating a first desired yaw rate of the vehicle (100) based on said determined current yaw rate of the vehicle and said determined rate of the vehicle's steering wheel (110) rotation, the desired yaw rate being further calculated based on the assumption that the driver applies a rate of steering wheel rotation as function of the driver's perceived error in yaw rate, and finally the step of providing said first desired yaw rate as an input to said vehicle movement control system (220) for controlling the vehicle.
Abstract:
The purpose is to obtain vehicle characteristics such that stable cornering can be executed when making a turn. An automobile (101) operation control method enables the relationship between the steering angle of a steering wheel (103a) and the roll angle of a vehicle body (111) to be modified depending on the speed of the automobile (101). An automobile operation control method is applied in particular to a personal mobility device including at least two or more front wheels and one or more rear wheels. In order to expand the range of application of vehicle characteristics for executing a stable cornering when making a turn of the automobile (101), the camber stiffness of the wheels is adjusted when making the turn by modifying the relationship between the roll angle of the vehicle body (111) and the roll angle of the wheels (110).
Abstract:
Method of eliminating a yaw disturbance (6) in a vehicle equipped with a managed braking system, said method comprising the following steps: estimating said yaw disturbance (6) in said vehicle as a function of a plurality of parameters, said plurality of parameters comprising a speed (3) of said vehicle, a yaw speed (1) of said vehicle, an angle of the front wheels (2) of said vehicle, an angle of the rear wheels of said vehicle, a maximum lateral acceleration (4) of said vehicle, and a yaw moment (5) caused by braking; and asymptotic elimination of said estimated disturbance (6) as a function of said speed (3) of said vehicle, said elimination consisting in making said estimated disturbance (6) inobservable with respect to the yaw speed (1) of said vehicle.
