Patent number: 11738754Abstract: A vehicle driving assistance system includes a travel route generation system that acquires travel road information and obstacle information acquired by sensor(s), and generates the target travel route, on which a host vehicle travels, on a travel road. When the host vehicle changes lanes, the system acquires information on three peripheral vehicles, which exist near the host vehicle, on a change destination lane from the obstacle information, sets a target space, to which the host vehicle 1 should move, between two each of the three peripheral vehicles on the change destination lane based on this information on the three peripheral vehicles, predicts a change in size of each of the target spaces, and generates the target travel route, on which the host vehicle travels during the lane change, on the basis of this predicted change in the size of each of the target spaces.Type: GrantFiled: January 29, 2021Date of Patent: August 29, 2023Assignee: MAZDA MOTOR CORPORATIONInventor: Takashi Sugano

Patent number: 11739703Abstract: A control system for a vehicle is provided, which includes a driving force source configured to generate torque for driving drive wheels, a steering angle related value sensor configured to detect a steering angle related value of a steering device, and a controller configured to control the torque to control the vehicle attitude based on the steering angle related value. The controller acquires a current traveling mode defining a response of acceleration or deceleration of the vehicle to an accelerator pedal operation. Based on the steering angle related value, when determined that a turning operation of the steering device in one direction is performed, the controller performs a torque decreasing control to add deceleration to the vehicle. When the acquired traveling mode is a high response traveling mode, the controller increases a reduction amount of the torque in the torque decreasing control more than in a low response traveling mode.Type: GrantFiled: February 11, 2022Date of Patent: August 29, 2023Assignee: Mazda Motor CorporationInventors: Daisaku Ogawa, Daisuke Umetsu
