Abstract: A zero point estimation device is configured to perform a first acquisition process, a second acquisition process, and a zero point estimation process. The first acquisition process is a process of acquiring a plurality of first detection values of a first sensor sampled at different timings from each other while a vehicle is traveling with a change in a direction of travel. The second acquisition process is a process of acquiring a plurality of second detection values of a second sensor sampled in synchronization with the sampling timings of the first detection values to be acquired by the first acquisition process. The zero point estimation process is a process of estimating a zero point of the second sensor by using, as inputs, the plurality of first detection values acquired by the first acquisition process and the plurality of second detection values acquired by the second acquisition process.

Abstract: A vehicle control device to be applied to a vehicle including parking brakes provided in association with right and left wheels and configured to be driven to bring the wheels into a non-rotatable state includes a processor. The processor is configured to acquire abnormality occurrence information on each of the right and left parking brakes. The processor is configured to, when an abnormality condition that a drive command is output to each of the parking brakes and one of the parking brakes has an abnormality is satisfied, control a device other than the parking brakes in the vehicle to suppress rotation of the wheel provided with the parking brake having the abnormality.

Abstract: A vehicle includes a sideslip preventing function of preventing a sideslip of the vehicle by separately adjusting a longitudinal force applied to each of the wheels. A controller controls the vehicle based on requests input from a driver assistance device, thereby causing the vehicle to travel autonomously. The controller calculates wheel lateral force request values based on the requests input from the driver assistance device. The wheel lateral force request values are request values of lateral forces acting on the respective wheels. The controller, when a behavior of the vehicle is in an oversteer state in a case in which the sideslip preventing function is failing, limits the wheel lateral force request values for the front wheels to values less than or equal to a first lateral force limit value, which is a limit value of the lateral force that can act on the rear wheels.

Abstract: A vehicle travel control apparatus includes an information acquiring section; a determining section that determines whether a special road terrain exists; and a speed control section that controls a speed of the subject vehicle. The speed control section is further configured to: when the special road terrain exists but a preceding vehicle does not exist, increase or decrease the speed of the subject vehicle with respect to a pre-set vehicle speed in the energy efficiency zone such that the energy efficiency is improved; and when the special road terrain and a preceding vehicle exists and the speed of the subject vehicle is planned to increase in the energy efficiency zone, control the speed of the subject vehicle in an inter-vehicle distance maintenance zone such that the subject vehicle has an inter-vehicle distance to the preceding vehicle longer than a pre-set inter-vehicle distance.
