摘要： A travel control device for a vehicle has a steered angle varying device 14 or a by-wire type steering device 96 which modifies a relationship of steered angle of steerable wheels to steering operation amount by a driver. When the control device decides that vehicle trajectory control is to be initiated or renewed, it calculates a target steered angle of the steerable wheels for driving the vehicle along a target trajectory which is required for the vehicle to arrive at a target arrival position in a target traveling direction on the basis of steering operation amount by a driver and vehicle speed at a time point of the decision. The control device controls the steered angle of the steerable wheels according to the target steered angle in feed-forward or feed-back manner.

摘要： A coordinate-control-gain calculation section 61 calculates a coordinate-control final control torque T_C required to properly control the traveling behavior of a vehicle, and determines a coordinate control gain Kg on the basis of the magnitude of this torque T_C. An arbitration-request determination section 62 determines the value of an arbitration request flag FRG_A on the basis of the magnitude of the torque T_C and the value of a flag FRG_L output so as to properly control the traveling behavior of a vehicle. On the basis of the value of the flag FRG_A and the magnitude of the coordinate-control arbitration torque Tr determined by use of the gain Kg, an arbitration section 63 selects the torque T_C or the torque Tr to be output as a post-arbitration control torque T_F. A post-arbitration drive control section 64 supplies to an electric motor a drive current corresponding to the determined torque T_F.

摘要： A vehicle information processing device mounted on a vehicle includes a future position calculating unit configured to calculate a future position of the vehicle based on steering input information corresponding to a steering input, a vehicle state amount that prescribes a turning state, and a vehicle speed, and an estimating unit configured to estimate a turning curvature of the vehicle at a provisional travel position ahead of a present position based on at least three vehicle positions according to the vehicle including at least the one calculated future position as well as including a vehicle position corresponding to the present position of the vehicle. As a result, a turning curvature of the vehicle at a vehicle position ahead of a present position can be estimated by a simple configuration and further the estimated turning curvature can be preferably used to stabilize vehicle behavior.

摘要： Information for generating a target speed pattern is computed from information acquired from various sensors and a running mode input switch, so as to generate the target speed pattern (S16). A process for determining whether to form a vehicle group or not calculates the difference between the target vehicle pattern of the own vehicle and a target speed pattern of another vehicle or vehicle group obtained through inter-vehicle communication, so as to determine whether to form the vehicle group or not (S22, S28, S32). This can determine whether to run solo or form a vehicle group according to a driver's demand.

摘要： An electric power steering device for a vehicle includes an estimation mechanism estimating if there is a possibility that a backward electric current flows in a booster circuit toward a vehicle battery device, and a boosting controller stopping the boosting operation of the booster circuit to prevent a backward electric current from flowing in the booster circuit when it is estimated that there is a possibility that a backward electric current flows by the estimation mechanism. The estimation mechanism estimates that there is a possibility that a backward electric current flows in the booster circuit when the steering condition of a steering wheel is a returning condition or a steering-held condition. Otherwise, the estimation mechanism estimates if a backward electric current flows on the basis of input and output voltages of the booster circuit and information on the switching of a first boosting switching element. Thereby, overheat of the booster circuit can be prevented.
