用于DPF再生的安全改进的装置和方法
摘要：
本发明涉及一种方法，其用于在包括具有发动机(230)、自动变速箱(240)和转矩变换器(237)的传动系的机动车辆(100)静止并且正在使得用于所述发动机(230)的排气的颗粒过滤器(320)再生时的安全改进，所述方法包括应用安全制动作用以使车辆(100)保持静止的步骤，尽管在所述传动系中维持转矩传递。所述方法还包括以下步骤：在所述变速箱(240)中选择高于所述变速箱(240)的初始齿轮速比差的齿轮速比差，以在所述车辆因此保持静止时减小传输到所述车辆的牵引轮(247a，247b)的转矩。本发明还涉及一种包含用于使计算机(200；210)实施根据本发明的方法的程序代码(P)的计算机程序产品。本发明还涉及一种用于在机动车辆(100)静止并且正在使得用于所述发动机(230)的排气的颗粒过滤器(320)再生时的安全改进的装置，并且本发明还涉及一种配备有所述装置的机动车辆(100)。
摘要（英）：

The invention relates to a method for safety improvement when a motor vehicle (100) comprising a power train with an engine (230), automatic gearbox (240) and torque converter (237) is stationary and particle filter (320) for the exhaust gases of the engine (230) is being regenerated, comprising the step of applying safety brake action to keep the vehicle (100) stationary despite torque transfer being maintained in said power train. The method comprises also the step of choosing in said gearbox (240) a gear step which is higher than an initial gear step of said gearbox (240) in order to reduce the torque transferred to the vehicle's tractive wheels (247a, 247b) when the vehicle is thus kept stationary. The invention relates also to a computer programme product comprising programme code (P) for a computer (200; 210) for implementing a method according to the invention. The invention relates also to a device for safety improvement when a motor vehicle (100) is stationary and a particle filter (320) for the exhaust gases of the engine (230) is being regenerated, and to a motor vehicle (100) equipped with the device.
