A vehicle collision avoidance assistance device is configured to perform forced braking or forced steering when a driver's vehicle has a possibility of colliding with an object ahead of the driver's vehicle, acquire at least one of information related to a condition of the driver's vehicle and information related to a situation around the driver's vehicle, determine, based on the acquired information, whether a request condition for requesting execution of the forced steering is satisfied and whether a forbiddance condition for forbidding the execution of the forced steering is satisfied, perform the forced braking when the request condition is not satisfied regardless of whether the forbiddance condition is satisfied, perform the forced steering when the forbiddance condition is not satisfied and the request condition is satisfied, and perform the forced braking when the forbiddance condition is satisfied though the request condition is satisfied.

An apparatus for preventing rolling of a vehicle operating in an automatic vehicle hold mode includes a reset determination unit configured to determine whether an automatic hold controller controlling an operation of the automatic vehicle hold mode has been reset, a mode determination unit configured to determine whether a mode of the vehicle is the automatic vehicle hold mode when it is determined that the automatic hold controller has been reset, and a vehicle control unit configured to brake the vehicle, based on at least one of a gear position, an opening degree of an accelerator pedal, and whether a brake pedal is operated, when it is determined that the mode of the vehicle is the automatic vehicle hold mode.

In some examples, a controller receives information of a route of a vehicle, and selects a first parameter set from among a plurality of parameter sets based on the route of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller causes application of the first parameter set to control a setting of the one or more adjustable elements of the vehicle.

A system, apparatus and method for controlling operation of a vehicle. Driver assistance system (DAS) data may be used for controlling one or more function of the vehicle via a driver assistance system. Driver profile data (DPD) is generated and/or received that includes training data from sensor monitoring of a driver's usage characteristics for at least one feature of a vehicle type during a driver-controlled mode of vehicle driving. The DPD is processed with the DAS data to determine if the DPD conform to one or more safety metrics. A driver profile data file may be created by weighing the portions of the DAS data with the DPD that do not conform with the safety metrics. One or more functions on the vehicle may be controlled via the driver profile data file using the driver assistance system during one of a semi-autonomous and fully autonomous mode of operation.

When a brake is turned on during travel of a hybrid vehicle, a required braking force required for a drive shaft is set based on a brake depression amount, a base rotation speed of an engine is set based on the required braking force, a shift stage is set based on the base rotation speed and a vehicle speed, a target rotation speed of the engine is set based on the shift stage and the vehicle speed, and the engine, the first motor, and the second motor are controlled such that the engine operates at the target rotation speed and the required braking force acts on the drive shaft.

A transmission is provided having a control module, an input member, an output member, four planetary gear sets, a plurality of interconnecting members, and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The torque transmitting devices include clutches and brakes. The control module includes a control logic sequence for performing a coasting downshift of the transmission.

A method and a corresponding device are provided for preventing an undesired vehicle motion during an automatic switch-off process of a drive machine in a motor vehicle. An automatic switch-off process is initiated by a start-stop apparatus before the standstill is reached if the motor vehicle is braked because of a deceleration request and the speed of the vehicle is less than a specified first speed threshold. A brake pressure of suitable magnitude is caused to be locked-in in the brake system even before the vehicle reaches the standstill if a first signal indicating that the vehicle standstill will soon be reached and a second signal indicating that an inability of the drive machine to operate in a self-sustaining manner will soon be reached are acquired because of an initiated automatic switch-off process of the drive machine.

A launch control method for a vehicle may include a step of increasing clutch torque of a clutch according to a decrease in braking pressure, a step of maintaining a current level of the clutch torque for a first reference duration, a step of gradually reducing the clutch torque within a range which is lower than the first reference torque level and is equal to or greater than a second reference torque level which is lower than the first reference torque level, a step of gradually increasing the clutch torque until the clutch torque reaches a third reference torque level which is higher than the first reference torque level, and a step of bringing the control to a stop when a state in which a clutch slip is less than a predetermined critical synchronous slip is maintained for a predetermined critical synchronization duration or longer than the predetermined critical synchronization duration.

A controller includes a processor programmed to determine, for a vehicle, a first control input based on input data and first reference parameters. The processor is further programmed to operate the vehicle according to the first control input. Based on operating data of the vehicle for an operating condition, the processor determines a second control input for the vehicle. Operating the vehicle according to the second control input reduces a cost of operating the vehicle relative to operating the vehicle according to the first control input. The processor is further programmed to determine, based on the second control input, second reference parameters. The controller generates a third control input based on the second reference parameters and the input data. A cost of operating the vehicle according to the third control input is reduced relative to the cost of operating the vehicle based on the first control input.

Provided are a driving assistance device and a driving assistance method using the same, which are capable of guiding safe parking-in or parking-out by increasing engine torque and applying the increased engine torque to an engine control unit when there is no movement of a vehicle during automatic parking-in control or automatic parking-out control of the vehicle at preset engine torque and brake pressure.
