  • Publication number: 20210107460
    Abstract: Accuracy of acquired parking space information on a parking space having a target parking range set therein is increased when the parking space information is registered. A vehicle parking assist apparatus (10) has a registration mode for registering the information on the parking space having the target parking range set therein, and a plurality of vehicle speed modes having different travel speeds of a vehicle (100) during execution of parking travel processing. The plurality of vehicle speed modes include two or more vehicle speed modes, one of which is selectable by a user. When the registration mode is not selected, during the execution of the parking travel processing, the vehicle parking assist apparatus (10) causes the vehicle (100) to travel in the vehicle speed mode selected by the user.

  • Publication number: 20210107564
    Abstract: A parking assistance apparatus obtains a target travelling route from a present position of a vehicle to a target parking position and controls the vehicle such that the vehicle moves along the target travelling route. The target travelling route is obtained such that the vehicle moves backward to reach the target parking position and the vehicle is moves in a region on the target parking position side of a travelling boundary line. The travelling boundary line is a straight line which is in front of the vehicle located at the target parking position and which is away from a reference position by a boundary distance. The reference position is a position at a front end and at a center in a lateral direction of the vehicle located at the target parking position. The boundary distance is a configurable value changed by a driver of the vehicle.

  • Publication number: 20200116083
    Abstract: A turbocharger including a compressor housing, a flange, an air bypass valve and a seal. The compressor housing has an impeller housing, an upstream passage positioned upstream of the impeller housing and a downstream passage positioned downstream of the impeller housing. The flange is coupled to the compressor housing and has a bypass passage connected to the downstream passage of the compressor housing and the upstream passage of the compressor housing. A groove is formed at a surface of the flange opposing the compressor housing and the seal is fitted into the groove. Therefore, a tight seal of the flange and the compressor housing can be ensured by the seal. Further, the air bypass valve is coupled only to the flange. Therefore, a tight seal of the turbocharger can be ensured easier than in a case where the air bypass valve is coupled over the flange and the compressor housing.
