摘要： A system for braking a vehicle is provided. The system comprises a powertrain comprising an electric machine arranged to propel the vehicle and a transmission arranged to transfer power between the electric machine and the driving wheels of the vehicle. The system further comprises a resistor device arranged to dissipate electric energy generated by the electric machine during braking of the vehicle, and an airflow generating device arranged to generate an airflow over the resistor device. The airflow generating device is arranged to be mechanically driven by the powertrain so as to generate said airflow. By (mechanically) driving the airflow generating device by means of the powertrain, the airflow generating device does not need its own motor, thereby making the system less complex. Further, the driving of the airflow generating device by means of the powertrain will consume energy itself, contributing to braking the vehicle.

摘要： The invention relates to a method for adapting control of a reducing agent dosing unit (237) in a reducing agent provision system for emission control of a combustion engine (231). Hereby characteristics relating to pressure variations associated with a dosing cycle are used for determining a first time period (topen) and a second time period (tclose). Said time periods are relating to a delay between activation of dosing and de-activation of dosing, respectively. Said first time period (topen) and a second time period (tclose) are used for adapting operation of said reducing agent dosing unit (237). The invention relates also to a computer program product comprising program code (P) for a computer (200; 210; 500) for implementing a method according to the invention. The invention relates also to a system for adapting control of a reducing agent dosing unit (237) in a reducing agent provision system for emission control of a combustion engine (231) and a motor vehicle (100) equipped with the system.

摘要： A method for discharging a capacitor (150, 350). An active discharge circuit (202; 302) is connected in parallel with the capacitor (150, 350). An interface (210; 310) provides a signal connection (211; 311) between a message-based communication system (148, 212) and the active discharge circuit (202; 302). The interface (210; 310) comprises at least one input (214, 216, 218, 220, 222) for receiving messages from the message-based communication system (148, 212). The interface (210; 310) comprises a wake-up functionality (224). The at least one input (214, 216, 218, 220, 222) comprises an input (218) for the wake-up functionality (224). The method comprises: receiving (401) at the input (218) for the wake-up functionality (224) a disable discharge command message of said messages for the disabling of the discharge of the capacitor (150, 350), wherein upon cessation of the disable discharge command message the discharge of the capacitor (150, 350) is enabled. An apparatus (200; 300) for the discharge of a capacitor (150; 350), wherein the apparatus (200; 300) comprises the interface (210; 310) and the active discharge circuit (202; 302) connectable in parallel with the capacitor (150; 350).
