Adjunto os pongo los parámetros que se toman como referencia para el tema de las transmisiones adaptativas en las zf de 6 marchas... espero que no sea repost! Adaptive transmission controlAs with earlier automatic transmissions, the 6-speed automatic transmissions offer the choice between a comfort program and a sport program. The adaptive transmission control (component of electronic transmission control) adapts the shift characteristics of the comfort program and sport program to the driver's wish and the driving situation. In both programs, the adaptive transmission control changes from a basic map to a performance-orientated map, as required: The adaptive transmission control takes the following demands into account: • Comfort program in selector lever position "D" The comfort program is based on 2 maps: The XE map (extreme economy) and the E map (economy). The EGS control unit normally selects the economical XE map (= basic map). In case of particular demands (e.g. load requirements), the system will change to the performance-orientated E map. If the input signals change in favour of a more gentle driving style, the system will change back to the more economical XE map. • Sport program in selector lever position "M/S" The sport program effects dynamic, sporty shift characteristics. In the sport program, there is the basic S map (sport) and the performance-orientated XS map (extreme sport). If an extremely dynamic driving style is called for, the system will change from the S map to the performance-orientated XS map. The adaptive transmission control takes the following demands into account:• Adaptation to driver type • Driving uphill or trailer towing • Driving downhill • Braking deceleration and automatic upshift • Winter program Adaptation to driver typeThe adaptation to different driver types is done using the following values: - Kick-fast If the accelerator pedal is depressed rapidly, the shift program is changed accordingly. This is achieved by the detected accelerator-pedal value being compared with threshold values in the EGS control unit. The result of this comparison is the proposal of one of the two possible programs (XE or E in comfort program, S or XS in sport program). - Cornering detection Cornering detection reacts to the vehicle's lateral acceleration with an indirect adaptation to the driver type. Lateral acceleration is considered an indirect statement of the preferred driving dynamics and does not cause an immediate gearshift response (shifts when cornering could adversely affect driving stability). Lateral acceleration is calculated from the signals from the wheel-speed sensors, from the yaw rate and road speed.- Brake evaluation The braking action is evaluated in a similar way to "kick-fast". The braking deceleration is measured and compared with threshold values in the EGS control unit. The result of this comparison is the proposal of one of the two possible programs (XE or E in comfort program, S or XS in sport program).Driving uphill or trailer towingThese functions are based on a comparison of actual car acceleration with a nominal value. From the current engine operating situation, the acceleration with normal load on a level surface is calculated. If the actual acceleration is significantly below the theoretical value, the "Driving uphill or trailer towing" function is activated. The design of the corresponding shift characteristics allows a high-speed driving style. Undesirable upshifts and frequent up/downshifts are eliminated or greatly reduced.Driving downhillIf the EGS control unit detects downhill driving, it will automatically shift down a gear if the vehicle's speed picks up. This enhances the engine's braking effect. A downshift is only effected if the engine speed is below the maximum speed of the lower gear. The EGS control unit detects downhill driving on the basis of signals from the throttle valve potentiometer (load), wheel speed sensor (road speed) and brake light switch (brake activation).Braking deceleration and automatic upshiftTo decelerate the vehicle, the foot is taken off the gas and the brake depressed as necessary. The gearshift map triggers an upshift when the throttle is closed. These gearshifts are not necessary in conjunction with brake applications as they prevent the engine's braking effect from being exploited. The intention to apply the brakes can often be anticipated from the accelerator pedal being rapidly released to the zero position. If such an action is detected, the upshift is suppressed for as long as the accelerator pedal is in the zero position and the vehicle is in overrun mode.Winter program (only with selector lever in position "D")The winter program is automatically activated if the drive wheels start to spin even at a low rate of acceleration. The winter program ensures better traction by not using 1st gear. Early upshifts reduced the reactions caused by load changes. The winter program is deactivated if the wheels do not spin for several seconds despite high drive torque.
Muy interesante, amplía los datos que suelen venir en el manual. En algunos apartados parece diferente del EGS del E38. En éste y si no me falla la memoria, quiero entender que hay 7 subprogramas entre ultra económico y ultradeportivo y la posición S bloquea el ultradeportivo. No estoy seguro al 100% pero si el manual está bien traducido eso es lo que parece indicar. En este caso del E65 parece que en D hay dos subprogramas (económico y supereconómico) y otros dos en S (deportivo y superdeportivo). Lo enlazo a la base de datos.
