An object detection device that detects a corner of an object includes: a transmitter that transmits a search wave; receivers that receive a reflected wave reflected off the corner. The device determines a first path length of the search wave from the transmitter to a first receiver, and uses the positions of the transmitter and the first receiver as focal points to find a first ellipse whose distances from the transmitter and the first receiver add up to the first path length. The device determines a second path length of the search wave from the transmitter to a second receiver, and uses the positions of the transmitter and the second receiver as focal points to find a second ellipse whose distances from the transmitter and the second receiver add up to the second path length. The device finds an intersection point between the first and second ellipses as the corner.

In a driving assist system, a driving assist device as a control device acquires driving control information to be used for performing a driving control process in which an own vehicle follows a preceding vehicle running on the same lane of the own vehicle in front of the own vehicle. The driving assist device performs the driving control process of the own vehicle based on the acquired driving control information. The driving assist device detects an interruption of a preceding-vehicle following of the own vehicle. In the preceding-vehicle following, the own vehicle follows the preceding vehicle running on the same lane. The driving assist device decelerates a vehicle speed of the own vehicle by using a predetermined braking force when detecting the interruption of the preceding-vehicle following of the own vehicle during the preceding-vehicle following.

An automatic following control execution unit recognizes a preceding vehicle of the own vehicle and performs automatic following control of causing the own vehicle to automatically follow the preceding vehicle. A start-command acquisition unit acquires a start command to initiate the automatic following control. An automatic following control starting unit starts the automatic following control, when the brake is switched from on to off after satisfaction of a first to fifth conditions. The first condition is that the own vehicle is not under the automatic following control. The second condition is that a brake of the own vehicle is in an on state. The third condition is that the own vehicle is at rest. The fourth condition is that the preceding vehicle has been recognized. The fifth condition is that the start command acquisition means has acquired the start command. A target stopping inter-vehicle distance setting unit detects a first inter-vehicle distance between the own vehicle and the preceding vehicle when the first to fifth conditions are satisfied, and sets, as the first inter-vehicle distance, a target inter-vehicle distance for stopping the own vehicle. A start timing setting unit detects a second inter-vehicle distance between the own vehicle and the preceding vehicle at the start of the automatic following control, and sets a start timing for starting the own vehicle on the basis of the second inter-vehicle distance.

A recognition support system includes: an object detection device detecting an object that is located in a periphery of a host vehicle; a direction sensing device sensing a direction to which a driver intends to turn the host vehicle; a range setting device setting a notification range based on the direction sensed by the direction sensing device; a selecting device defining the object, which is detected by the object detecting device, as a specified object when the object moves independently from the host vehicle, and selecting the specified object, which is located within the notification range, to be presented to the driver based on a state of the specified object; and an information presenting device presenting an information enabling the driver to recognize the specified object selected by the selecting device.

A control apparatus for a vehicle includes processing circuitry. The processing circuitry calculates a target torque such that the greater the amount of brake operation is, the smaller the target torque becomes. The processing circuitry controls the drive motor such that the creep torque is smaller when brake operation is being performed by the driver than when the brake operation is not being performed by the driver. The control circuitry controls the brake device such that, when the brake operation is being performed by the driver, the brake torque approaches a target brake torque. The processing circuitry sets a decrease gradient of the creep torque to be smaller than a decrease gradient of the target torque when the brake operation amount is increased under a condition in which the creep torque is being output by the drive motor.

Control apparatus for vehicle

A braking device for a vehicle is provided which includes a braking simulator, thus resulting in improved mountability of the braking device in the vehicle. The braking device is designed to permit component parts of the hydraulic booster to slide on one another in response to a braking effort on a brake pedal, thereby absorbing an undesirable load on the braking device and also ensuring the stability in operating the brake pedal. This results in improved durability and maneuvering feeling of the braking device.

Brake system for vehicle designed to improve durability and maneuvering feeling

A braking device for a vehicle is provided which includes a hydraulic booster to make wheels of the vehicle produce frictional braking force, a solenoid valve installed in a flow path connecting between a brake fluid accumulator and a servo chamber of the hydraulic booster, and a collision avoidance controller. When determining that there is a risk of a collision with an obstacle, the collision avoidance controller opens the first solenoid valve to achieve emergency braking to minimize the risk of the collision. Basically, the emergency braking is achieved only using the solenoid valve, thus allowing an emergency avoidance mechanism of the braking device to be constructed with a minimum of equipment and facilitating the mountability of the braking device in vehicles.
