Abstract: The invention relates to a method and arrangement for determining a current road inclination, specifically taking into account a quality measure for the determination. The invention also relates to a corresponding computer program product. The method comprises the steps of: —measuring (S1), a first vehicle operating parameter; —receiving (S2) the first vehicle operating parameter; —determining (S3) an indication of a quality level for the first vehicle operating parameter, and —determining (S4) an estimated value of the current road inclination based on the first vehicle operating parameter and the indication of the quality level for the first vehicle operating parameter.

Abstract: The invention relates to a drive arrangement for a vehicle and a method for gear shifting in a vehicle. The drive arrangement (5) comprises at least a first drive axle (10, 20, 30) operatively connected to a first gear box (11) and a first propulsion unit (12). The drive arrangement (5) further comprises a second gear box (21) and a second propulsion unit (22) operatively connected to the first drive axle (10) or to an optional second drive axle (20, 30). The drive arrangement (5) further comprises at least one electronic control unit (ECU) adapted to govern gear transmission of the first and the second gear boxes (11, 21). The electronic control unit (ECU) is configured to automatically select between shifting gear on the first and the second gear boxes (11, 21) simultaneously, or sequentially. The drive arrangement and the method provides for a very versatile drive arrangement and gear synchronization providing comfort for the driver and the passengers as well as improved vehicle dynamics.

Abstract: A method is provided for determining when to allow a vehicle engine to be placed in an engine standby mode. Various conditions, such as driver-controlled conditions, vehicle conditions, and energy management conditions, are compared to corresponding predetermined conditions. If at least some of the conditions match their corresponding predetermined conditions, the vehicle engine is allowed to be placed in a standby mode.

Abstract: Rapidly changing torque demand is coordinated in an automotive vehicle having an engine and at least one motor. An engine base torque level indicating slowly changing torque produced by the engine is received. A motor torque is determined as a difference between a fast desired torque and the engine base torque level. An engine fast torque is determined as a difference between the request for fast desired torque and the motor torque. The motor torque is determined as a motor torque request and the engine fast torque is determined as an engine torque request.

Abstract: Torque demand is coordinated in a vehicle. Information defining at least one torque production limitation for a first torque producing device is received. A request for torque is compared with the first torque producing device torque production limitation. If the comparison does not result in the request for torque exceeding a limitation, a first coordinated torque request is determined as the request for torque and a null torque is determined as a second coordinated torque request. Otherwise, a first excess requested torque is determined as the difference between the request for torque and the exceeded limitation, the first coordinated torque request is determined as the exceeded limitation, and the second coordinated torque request is determined as the first excess requested torque.
