摘要： The invention relates to a method for the quality assurance of exhaust gas behaviour in a motor vehicle (100), particularly in a hybrid vehicle, comprising: monitoring (10) an on-board-diagnosis (OBD) function (110); providing (20) a journey counter (120), a diagnosis counter (130), and a nominal diagnosis frequency value (140); incrementing (50) the journey counter (120) following the beginning of a driving cycle; generating (60) an actual diagnosis frequency value (160) using a combination of the diagnosis counter (130) and the drive counter (120); and establishing (70) a difference between the nominal diagnosis frequency value (140) and the actual diagnosis frequency value (160). If the difference falls short of a threshold: a control method (170) is selected (75), which is designed to successfully complete a currently running OBD of the OBD function (110) and to initiate and complete a non-running OBD. Following the completion of the OBD of the OBD function (110), the diagnosis counter (130) is incremented (80) and the motor control restored (90) to an original motor control. The invention further relates to a corresponding device (200) and to a corresponding motor vehicle (100).

摘要： In motor double-drive mode, a first rotation speed (Np1) and a second rotation speed (Np2) as a drive shaft rotation speed are calculated from rotation speeds (Nm1, Nm2) of motors (MG1, MG2) on the assumption that an engine rotation speed is zero (S110). A state where a difference (Npl - Np2) between the first rotation speed and the second rotation speed is larger than a threshold (Npref) continues, and, when a malfunction counter (CW) becomes larger than a threshold (CWref), it is determined that there is a malfunction in a one-way clutch (CL1) or pinion gears (S140 to S180). At a start of the engine, it is determined that there is a malfunction in the one-way clutch (CL1) when the engine rotation speed (Ne) is normally increasing (S240), and it is determined that there is a malfunction in the pinion gears when the engine rotation speed (Ne) is not normally increasing (S260).

摘要： In a vehicular braking control apparatus, a target regenerative braking force and a target factional braking force are calculated on the basis of a reference vehicle deceleration Gbt based on an amount of braking operation performed by a driver. Braking forces are usually controlled in a cooperative braking mode realized by regenerative braking and frictional braking (S100 to S210). Braking forces for wheels are controlled in a single braking mode realized by the frictional braking when a braking control is performed for the first time or for the last time in a predetermined number of times, and a correction coefficient (Kp) is calculated as a ratio of a reference vehicle deceleration (Gbt) to an actual vehicle deceleration (Gbx) during the braking control (S90, S220 to S280). The target frictional braking force is corrected by being multiplied by Kp (S190). Hence, a total braking force for the vehicle is prevented from fluctuating when the braking force control mode shifts between the cooperative braking mode and the single braking mode. Thus, the vehicle deceleration is prevented from abruptly changing (S110 to S210).

摘要： An autonomous driving vehicle (ADV) speed following system determines how much and when to apply a throttle or a brake control of an ADV to maneuver the ADV around, or to avoid, obstacles of a planned route. The speed following system calculates a first torque force to accelerate the ADV(801), a second torque force to counteract frictional forces and wind resistances to maintain a reference speed(802), and a third torque force to minimize an initial difference and external disturbances thereafter between predefined target speed and actual speed of the ADV over a planned route(803). The speed following system determines a throttle-brake torque force based on the first, second, and third torque forces(804) and utilizes the throttle-brake torque force to control a subsequent speed of the ADV(805).

摘要： A hybrid vehicle is taught herein in which a clutch is disposed between an engine and a motor/generator and disengagement of the clutch is controlled in a coasting drive while dragging the engine. A drive controller engages the clutch so that the vehicle coasts while dragging the engine at a time of coasting deceleration. While coasting, when the stepped transmission of the hybrid vehicle downshifts, the clutch is disengaged during the downshift.
