A driver assistance system for vehicles, which is capable of preventing driver carelessness from causing a vehicle accident when a vehicle stops while traveling, includes a vehicle sensor unit configured to detect driver state data, a driver assistance unit operated to assist a driver when driver carelessness about vehicle driving is detected when a vehicle stops while traveling, and a control unit configured to identify whether the driver is careless based on the driver state data when the vehicle stops while traveling, and to operate the driver assistance unit when the driver carelessness is detected, preventing the vehicle from driving.

A propulsion system, control system, and method use model predictive control systems to generate a plurality of sets of possible command values and determine a cost for each set of possible command values. The set of possible command values that has the lowest cost is determined and defined as a selected set of command values. In some circumstances, the MPC-determined command value may be replaced by another transmission ratio command based on override inputs. Minimum and maximum transmission ratios are determined based on the override inputs, and a constrained (or arbitrated) transmission ratio is determined therefrom. The constrained or arbitrated transmission ratio is used to determine whether to apply an MPC-determined transmission ratio or a transmission ratio based on the arbitrated transmission ratio to determine an ultimate commanded transmission ratio. Pressure(s) are commanded to a transmission pulley assembly, which is configured to implement the ultimate commanded transmission ratio.

A vehicle control method includes, by a controller, while an engine is auto-stopped and an electric parking brake is engaged, auto-starting the engine without releasing the electric parking brake responsive to application of an accelerator pedal less than a predefined amount, and auto-starting the engine and releasing the electric parking brake responsive to application of the accelerator pedal greater than the predefined amount. The method also includes comprising auto-stopping the engine and engaging the electric parking brake responsive to vehicle speed being less than a predefined threshold speed.

A gear change method for an electric transmission system (1), the electric transmission system (1) including an electric machine (2), a multi-stage transmission (3) drivingly connected downstream from the electric machine (2) and having interruption of tractive force, and at least one brake (4) for braking a vehicle wheel (5), the method including transferring the brake (4) out of an inoperative condition into a readiness condition during a gear change operation of the transmission (3).

A method of automatically activating a high-torque braking system in a heavy-duty vehicle configured to operate in at least one low speed, high torque mode and at least one higher speed, lower torque mode is disclosed. The method includes determining a speed-controller device such as a joystick or lever of the vehicle is in a first position which results in the vehicle travelling in a higher-speed, lower-torque mode, and, responsive to detecting braking and a change in position of the speed-controller from the first position to a second, neutral, position, activating a low-speed high torque mode of operation for braking the vehicle.

A determination method for a drive force to be requested for a hybrid vehicle, and an apparatus. The determination method comprises the following steps: obtaining a gear state, a current vehicle speed, a current gas pedal degree of engagement, and drive force mapping information of a vehicle, the drive force mapping information indicating a correspondence relationship between vehicle speed, gas pedal degree of engagement, and drive force; if the gear state is such that the vehicle is not in park gear or neutral gear, obtaining a driving mode and altitude data of the vehicle; and if the altitude data is less than a preset altitude, determining a drive force to be requested for the vehicle on the basis of the current vehicle speed, the current gas pedal degree of engagement, the driving mode, and the drive force mapping information.

A hybrid vehicle includes two drive sources and two clutches, and is switchable between a neutral mode and a parallel mode during vehicle traveling. The two drive sources are both disconnected from drive wheels in the neutral mode, and are both connected to the drive wheels in the parallel mode. A control method for the hybrid vehicle includes implementing at least one of a first switching control and a second switching control. The first switching control includes, upon switching from the neutral mode to the parallel mode, implementing two synchronization controls on rotational speeds before and after the two clutches, concurrently during at least a partial period. The second switching control includes, upon switching from the parallel mode to the neutral mode, implementing two controls to cause transmitted torques of the two clutches to respectively approach zero, concurrently during at least a partial period.

An engine control method for preventing an engine of a vehicle from stalling on a sloped road includes steps of: detecting whether a shifting lever is in a neutral stage (N-stage); measuring a vehicle speed and a slope angle of the sloped road, and calculating a load acting on a vehicle body on the sloped road; accelerating an engine a first time to increase an engine RPM so that an engine torque is larger than the load; and accelerating the engine a second time to move the vehicle when the shifting lever enters into a driving gear stage (D-stage).

A method for controlling vehicle operation of a vehicle having a standard transmission, a clutch, a service brake activated by a brake pedal, and an engine controller configured to shut off the engine after a stationary state of the vehicle has been reached. The method including shutting off the engine in a stopping step if an idling position of the manually shifted transmission has been engaged and if the clutch has been engaged and restarting engine in a chronologically subsequent starting step upon activation of a pedal, including a clutch pedal. The service brake configured to apply a brake pressure directly after release of the brake pedal for predetermined time period or interval between the stopping step and the starting step.

A vehicle controlling device has a frictional engagement element provided between a drive motor and a driving wheel; a shifting unit capable of selecting a travel range or a non-travel range; first obtaining unit configured to, during selection of the travel range, obtain a first parameter including at least a first motor torque value that is a torque value of the drive motor; second obtaining unit configured to, during selection of the non-travel range, obtain a second parameter including at least a second motor torque value that is a torque value of the drive motor; and operating unit configured to, on the basis of the first and second parameters, calculate a zero point hydraulic pressure command value at which the frictional engagement element starts to generate a torque capacity. It is therefore possible to detect a zero point of a clutch between the drive motor and the driving wheel.
