Vehicle control device
A vehicle control device includes: a target traveling path setting unit that sets a target traveling path of an own vehicle; a reference position setting unit that sets a reference position of the own vehicle for specifying a position of the own vehicle with respect to the target traveling path; and a control unit that controls a steering assist amount of a steering wheel, based on a positional deviation being a deviation between the target traveling path set by the target traveling path setting unit and the reference position of the own vehicle set by the reference position setting unit. The reference position setting unit changes the reference position according to a vehicle speed.
LANE DEPARTURE SUPPRESSION DEVICE
A lane departure suppression device including a control unit that executes a lane departure suppression control (automatic steering of the steering wheel and/or a warning being issued) when it is determined that there is a possibility that a vehicle departs from a lane. The control unit does not execute the lane departure suppression control when the control unit determines that a lateral speed and a lateral acceleration of the vehicle are increased within a predetermined time from a time point at which acceleration and deceleration of the vehicle is started, and that there is an adjacent lane on a side with respect to the lane in which the lateral speed and the lateral acceleration are increased.
Method and Device for Calculating Running Resistance of Vehicle
A method for calculating running resistance of a vehicle includes: calculating, by a controller, an integrated value obtained by integrating a torque of a driving source of the vehicle before the vehicle reaches a reference speed after the vehicle starts; and calculating, by the controller, the running resistance of the vehicle including rolling resistance based on the integrated value of the torque of the driving source.
