Abstract: A suspension control device includes: a parameter storage unit that stores a parameter indicating a correspondence between behavior information indicating behavior of a vehicle and sensor data related to a suspension of the vehicle, the parameter determined in advance by machine learning; a vehicle behavior inference unit that receives the behavior information among communication data transmitted in the vehicle and infers the sensor data related to the suspension of the vehicle based on the behavior information and the parameter in the parameter storage unit; and a control value calculation unit that calculates a suspension control value for controlling the suspension based on the inferred sensor data.

Abstract: A circuit board of an electronic control device has a surface to which a connector is attached and on which a heat generating component is mounted. A metal casing that stores therein the circuit board has an opposing surface that faces the surface of the circuit board on which the heat generating component is mounted. A first fin that protrudes toward the surface on which the heat generating component is mounted is provided on the opposing surface of the casing. The first fin overlaps the heat generating component in the thickness direction of the circuit board.

Abstract: In a vehicle control device 100, a rough-road travel unit 1008 determines whether or not there is a rough road within a predetermined range in front of a vehicle based on a position of the vehicle estimated by a position estimation unit 1001 and a position of a rough road acquired by a map information acquisition unit 1011, and determines whether or not the rough road has been detected based on road surface information acquired by an outside environment information acquisition unit 1002. When it is determined that there is the rough road within the predetermined range in front of the vehicle based on the position of the vehicle estimated by the position estimation unit 1001 and the position of the rough road acquired by the map information acquisition unit 1011, and it is determined that the rough road is not detected based on the road surface information acquired by the outside environment information acquisition unit 1002, a rough-road detection-omission determination unit 1006 determines whether or not rough-road detection is omitted based on the position of the rough road and a detectable section of a stereo camera 200.

Abstract: An object of the present invention is to provide an electronic control device that can be improved in EMC resistance when a resin case is used without using a metal case. An electronic control device of the present invention includes: a substrate 101; an electronic component 302 disposed on an electronic component mounting surface 101a of the substrate 101; and a resin case 100 that houses the substrate 101. The case 100 includes a conductive member 102 on a surface facing the electronic component mounting surface 101a of the substrate 101. The substrate 101 includes a plurality of conductive surface-mounted members 301 mounted on the electronic component mounting surface 101a to surround the electronic component 302. The plurality of conductive surface-mounted members 301 are arranged to be separated from each other on the electronic component mounting surface 101a and form electrical shielding by coming into contact with the conductive member 102.

Abstract: A vehicle control device is provided which has enhanced robustness against a shielding object, further, which does not measure a received radio wave from a radio transmitter and which can continue, for example, automatic driving control by comparing two types of vehicle positions calculated using the radio transmitter installed outside a vehicle and a sensor mounted on the vehicle and detecting an error in order to reduce a detection error of the radio transmitter due to a failure in communication of the radio transmitter. Two types of vehicle positions calculated using the sensor mounted on the vehicle and the radio transmitter are compared, and it is determined that the radio transmitter is affected by a shielding object in a case where a temporal change of a vehicle position deviation and/or a behavior change of a vehicle position (first own vehicle position) based on the radio transmitter is detected.

Abstract: A valve seat member is provided in a cap member. A first sub valve is provided in another side chamber. A second sub valve is provided in a cap chamber formed between a bottom portion of the cap member and the valve seat member. In a second passage, an orifice is disposed on an upstream side or a downstream side from the first sub valve in flow by which the first sub valve is opened. In a region in which a piston speed is low, a valve of a second damping force generating mechanism is opened in a state in which a valve of a first damping force generating mechanism is closed. In a speed region in which the piston speed is higher than in another region, the valve of the first damping force generating mechanism and the valve of the second damping force generating mechanism are both opened.
