Methods and systems are provided for controlling and diagnosing a mechanical vehicle component. In one example, a method may include determining a vehicle speed and a plurality of clutch position settings at a diagnostic controller, and identifying unauthorized conditions based on these determinations. Further, the diagnostic controller may trigger an active fault state of the mechanical vehicle component in order to avoid unauthorized conditions that may lead to unwanted or unanticipated changes in vehicle motion.

A collision determination apparatus includes an acquisition section, a filtering section, a target object information detection section, a target object path prediction section, an own vehicle path prediction section, a collision determination section, and a vehicle control section. The acquisition section (21) acquires detection information based on a reflected wave from a search device. The filtering section filters the detection information. The target object information detection section detects a position of a target object using the filtered detection information. The target object path prediction section predicts a path of the target object based on changes in the detected position of the target object. The own vehicle path prediction section predicts a path of an own vehicle. The collision determination section determines a risk of collision between the own vehicle and the target object. The vehicle control section executes a vehicle control. The path of the target object is predicted based on the detection information filtered by a collision determination filter. The path of the target object is predicted based on the detection information filtered by a vehicle control filter. The filtering process is a smoothing process that inhibits changes in the detection information. The vehicle control filter and the collision determination filter have different smoothing degree of inhibiting the changes in the detection information.

In a case where a predetermined switching operation to a state in which a traveling position is selected from a state in which another shift position of a mechanical transmission device is selected is performed by a driver, a quick engagement command to quickly engage a predetermined engagement device is performed in a state in which output of a predetermined torque is stopped, and then a rapid garage control of increasing a rotation speed of an electric motor at a rotation speed equal to or higher than a predetermined rotation speed is executed. The rapid garage control is executed in a case where a predetermined start condition is established.

Systems and methods for controlling engine brake disengagement in a vehicle include a controller receiving a signal indicative of a command to disengage an engine brake while the vehicle engine is in engine brake engaged condition. The engine can be subjected to a first negative torque under the engine brake engaged condition. The controller can cause the engine brake to be gradually disengaged over a time period using a predefined torque ramp rate, responsive to the signal. The gradual disengagement of the engine brake can be in the form of a phased out disengagement, and can reduce vehicle engine jerk associated with engine brake disengagement.

The ADAS monitoring event system of the present invention has the advantages of checking whether an advanced driver assistance system (ADAS) is operating appropriately and a state during driving based on vehicle-related data, increasing the safety of autonomous driving, and resolving disputes in the event of a traffic accident.

A system comprises an autonomous vehicle (AV) and a control device operably coupled with the AV. The control device detects a series of events within a threshold period of time, where a number of series of events in the series of events is above a threshold number. The series of events taken in the aggregate within the threshold period of time deviates from a normalcy mode. The normalcy mode comprises events that are expected to the encountered by the AV. The control device determines whether the series of events corresponds to a malicious event, where the malicious event indicates tampering with the AV. In response to determining that the series of events corresponds to the malicious event, the series of events are escalated to be addressed.

A mild hybrid vehicle and a method of controlling the same are provided. The mild hybrid vehicle includes a sensor that detects shift intention of a driver to provide the shift intention as sensing information, a controller that determines a target rotation speed of an MHSG based on the sensing information and controls the MHSG based on the target rotation speed, and the MHSG that controls the rotation speed of the engine under control of the controller when the shift intention is detected.

A hybrid vehicle includes an engine, a motor, and a controller. The controller is configured to control the engine and the motor. The controller is configured to, when the engine is operated under load at the time when the vehicle slows down and stops in an autonomous driving mode in which the vehicle runs without driver's operation, set a controlling lower limit rotation speed of the engine to a maximum rotation speed out of a plurality of candidate rotation speeds and control the engine such that the engine is operated under load within a range higher than or equal to the controlling lower limit rotation speed.

Systems and methods are provided for controlling a transmission. An engine stop-start event may be allowed or denied based on one or more characteristics of the vehicle including the transmission.

The apparatus and system for integrating an electric motor into a vehicle may convert a vehicle from an internal combustion vehicle to a hybrid-electric vehicle. One or more electric motors may be integrated into a powertrain between an internal combustion engine and a transmission. A supervisory controller may monitor and control operation of the internal combustion engine, clutching assembly, transmission, one or more electric motors, or any combination thereof to add mechanical power to the powertrain, remove mechanical power from the powertrain, or neutrally balance the transfer of mechanical power between the powertrain and the one or more electric motors. This conversion may be operable to produce torque from both internal combustion and electrical sources and may be operable to recover energy via regenerative braking. The conversion may be performed with little downtime and with the basic fundamental knowledge of a savvy car enthusiast.
