Abstract: An electronic control unit executes throttle torque reduction control for decreasing an engine torque by reducing a throttle opening degree during an upshift of an automatic transmission with respect to the throttle opening degree before a start of the upshift. During the upshift of the automatic transmission, the electronic control unit actuates a waste gate valve in a closing direction with respect to a position of the waste gate valve before the start of the upshift in parallel with execution of the throttle torque reduction control. Thus, a decrease in supercharging pressure due to execution of the throttle torque reduction control is suppressed during the upshift, and the engine torque that has been temporarily decreased in an inertia phase of the upshift recovers immediately after the upshift, so it is possible to suppress deterioration of drivability.

Abstract: A torque sharing rate is set as a constraint of a motion equation of an automatic transmission by using a gear shift model in which gear shift target values are set by two values of a torque on a rotating member on an output shaft side and a rotation speed variation of a rotating member on an input shaft side. In addition, a first gear shift according to the gear shift control and a second gear shift that uses a gear shift model in which the gear shift target value is set using only the velocity variation of the rotating member on the input shaft side to enable a speedier gear shift than the first gear shift are selectively executed.

Abstract: A collision determination apparatus receives sensor data, which includes a sensor identifier, from multiple sensors that are of at least two different sensor types. Based on the sensor data from each of the sensors, a main determination unit determines whether to operate a protection apparatus. In parallel, a redundant determination unit determines whether to operate the protection apparatus based on at least one sensor data and by switching sub-determination units that have different determination logics according to a sensor type. In particular, the sensor identifier includes a sensor type information that allows the redundant determination unit to determine the sensor type of the sensor that transmitted the sensor data, and select the appropriate sub-determination unit. Therefore, based on the sensor type information in the sensor data, the same collision determination apparatus can be used in different vehicles that have respectively different number of sensors and different sensor types.

Abstract: In a method for signaling a braking process on a trailer vehicle coupled to a towing vehicle, at least one light on the trailer is actuated with an emergency brake signal during emergency braking and with a normal signal during a different driving state. The emergency brake signal causes a different actuation of the light than does the normal signal. The light can be actuated by a control signal of the towing vehicle, and the actuation state of the light can be influenced by at least one control device on the trailer. The control device detects the control signal generated by the towing vehicle and fed to the trailer to actuate the light, and analyzes the control signal. If it detects that the control signal is an emergency brake signal, it does not carry out a dedicated actuation of the light, or it effects a different actuation of the light than in other cases.

Abstract: A vehicle is provided that may distinguish between dynamic obstacles and static obstacles. Given a detector for a class of static obstacles or objects, the vehicle may receive sensor data indicative of an environment of the vehicle. When a possible object is detected in a single frame, a location of the object and a time of observation of the object may be compared to previous observations. Based on the object being observed a threshold number of times, in substantially the same location, and within some window of time, the vehicle may accurately detect the presence of the object and reduce any false detections.
