Vehicle control device and control method for vehicle
A vehicle control device includes an external sensor configured to acquire environmental information around a host vehicle, and an electronic control unit. The electronic control unit is configured to control the host vehicle so that the host vehicle travels along a target travel trajectory; detect an adjacent preceding vehicle that is traveling in a lane adjacent to a lane in which the host vehicle is traveling; acquire environmental information on a road side or a lane on an opposite side of the lane in which the adjacent traveling vehicle is traveling from the lane in which the host vehicle is traveling; and generate the target travel trajectory of the host vehicle so as to move away from the adjacent preceding vehicle in a width direction of the lane in which the host vehicle is traveling, within a lane width of the lane in which the host vehicle is traveling.
Trajectory tracking with four-wheel steering
Four-wheel steering of a vehicle, e.g., in which leading wheels and trailing wheels are steered independently of each other, can provide improved maneuverability and stability. A first vehicle model may be used to determine trajectories for execution by a vehicle equipped with four-wheel steering. A second vehicle model may be used to control the vehicle relative to the determined trajectories. For instance, the second vehicle model can determine leading wheels steering angles for steering leading wheels of the vehicle and trailing wheels steering angles for steering trailing wheels of the vehicle, independently of the leading wheels.
METHOD FOR REAR STEERING CONTROL OF A VEHICLE
A method of controlling rear wheel steering in a vehicle including determining a stability state of the vehicle from a plurality of vehicle sensor inputs, determining a target vehicle performance based on the stability state of the vehicle, and determining a target rear angle of rear vehicle wheels based on a difference between a target vehicle characteristic and a model vehicle characteristic, wherein the target vehicle performance promotes agility and stability to a target model at different times based on the stability state of the vehicle.
SYSTEM AND METHOD OF ADJUSTING STEERING DAMPING BASED ON SOUND FREQUENCY ANALYSIS
A system for adjusting steering damping based on sound frequency analysis includes: an acoustic main body configured to play music and determine whether the music is being played; a sound collection device configured to collect a sound signal of the music being played; a sound frequency analysis device configured to receive the sound signal of the music collected by the sound collection device and determine whether the collected music has a strong beat; and a power steering electronic control unit electrically connected to the sound frequency analysis device and configured to receive a determination result of the sound frequency analysis device and adjust the steering damping according to the received determination result of the sound frequency analysis device.

Based on the planned traveling route, the second control unit is configured or programmed to cause the braking device to perform setting about braking of either the first or second wheels by performing pumping control.
STEERING CONTROL DEVICE
A steering control device includes a torque command value calculating unit configured to calculate a torque command value which is a target value of a motor torque when operation of a motor is controlled such that the motor torque is generated. The torque command value calculating unit includes a first component calculating unit configured to calculate a first component, a second component calculating unit configured to calculate a second component, and a torque component calculating unit configured to calculate a torque component. The first component calculating unit is configured to add a calculational hysteresis component to the first component such that hysteresis characteristics with respect to change of a specific state variable are provided. The torque component calculating unit is configured to perform calculation in a first calculation situation and calculation in a second calculation situation.
WORKING VEHICLE
A position detector is supported to be movable between a first position and a second position lower than the first position. A mounting stay is below the position detector when the position detector is in the first position, and, when the position detector is rotated together with the mounting stay from a state in which the position detector is in the first position, the position detector is moved to the second position and the mounting stay is positioned above the position detector in the second position and covers over the position detector so as to restrain the automatic steering control.
