Abstract: The vehicle 1 includes a tow vehicle 2 and a loading platform 3. The loading platform 3 includes a ROM 23 storing loading platform information including a loading platform type and a plurality of first external sensors 8 that detect an object around the loading platform 3. The tow vehicle 2 acquires the loading platform type from the loading platform 3 and includes an ADAS ECU 10 that performs a driving assist of the vehicle 1 based on the acquired loading platform type and a plurality of second external sensors 9 that detect an object around the tow vehicle 2. The ADAS ECU 10 converts the acquired detection data of each of the first external sensors 8 from a sensor coordinate system of each first external sensor to a loading platform coordinate system, further converts from the loading platform coordinate system to the tow vehicle coordinate system, integrates detection data of the first external sensor 8 and detection data of the second external sensor 9 into the tow vehicle coordinate system, and calculates the relative position and the relative speed of the detected object based on the integrated detection data.

Abstract: A suspension control apparatus includes: a variable damper; a communication unit provided inside a vehicle to receive a dynamic map from a cloud; and a controller configured to adjust a force generated by the variable damper. The controller includes: a state estimation unit, which is provided inside the vehicle, and is configured to detect a motion of the vehicle; an operation-stability controller configured to calculate an AFB command value for the variable damper based on internal information output from the state estimation unit; and a dynamic-map controller configured to calculate an FF command value for the variable damper based on the dynamic map received from the communication unit. The controller determines a command value for the variable damper from the AFB command value and the FF command value.

Abstract: A vehicle control device causes an automatic brake to function even for an obstacle suddenly appearing from outside a sensor detection range in a place estimated to be dangerous such as an intersection. A vehicle control device calculates time-to-collision TTC based on a detection result of an obstacle sensor, and controls a brake, which is an actuator of a vehicle, based on the calculated time-to-collision TTC. The vehicle control device includes a determination unit that determines right turn or left turn of the vehicle, and a command unit that sends a command according to a determination result of the determination unit to the brake. When determining that the vehicle is turning right or left, the determination unit changes the time-to-collision TTC to a longer value by extending more than that at the time of traveling straight.
