A method and a system for control of a combustion engine in a vehicle is presented. According to the present invention, at least one future speed profile vsin ICE off for an actual speed Vact of the vehicle is simulated during a road section ahead. The simulation is based on information about the road section and on knowledge that coasting with the combustion engine shut down will, at least initially, be applied during the road section. Subsequently, based at least on the at least one future speed profile vsin ICE off, starting point in time t ICE start is determined, when the combustion engine will need to be started because of a requirement for a forward driving force for the vehicle and/or a need to brake the vehicle. Subsequently, a starting point brought forward in time, t ICE pre_start, is determined, which precedes the starting point in time tICE start. Thus, according to the present invention, the starting point brought forward in time, tICE pre start, will occur before the starting point in time tICE start, which is determined based on the need for a forward driving or braking force arising. Subsequently, the combustion engine is controlled to be started at the starting point brought forward in time, tlCE_pre_start.

The present invention relates to a method and a system arranged for the control of a combustion engine in a vehicle. According to the invention, at least one future speed profile vSim coast for an actual speed vact of the vehicle during a road section is simulated. The simulation is based on information about the road section, and assumes that coasting will at least partly be applied during the road section. Subsequently, an applicability for coasting during the road section is evaluated. Subsequently, it is evaluated whether the combustion engine may be shut down during a coasting for at least a part of the road section that is deemed applicable. The evaluation of the shutdown of the combustion engine is here based at least on whether one or several system conditions for engine shutdown have been met, on one or several properties for one or several brake systems in the vehicle, and on a shutdown period TICE_off, when the combustion engine could be shut down. The combustion engine is then controlled based on this evaluation of turning off the engine.

ADAS&ME (Adaptive ADAS to support incapacitated drivers &Mitigate Effectively risks through tailor made HMI under automation) will develop adapted Advanced Driver Assistance Systems, that incorporate driver/rider state, situational/environmental context, and adaptive interaction to automatically transfer control between vehicle and driver/rider and thus ensure safer and more efficient road usage. To achieve this, a holistic approach will be taken which considers automated driving along with information on driver/rider state. The work is based around 7 provisionally identified Use Cases for cars, trucks, buses and motorcycles, aiming to cover a large proportion of driving on European roads. Experimental research will be carried out on algorithms for driver state monitoring as well as on HMI and automation transitions. It will develop robust detection/prediction algorithms for driver/rider state monitoring towards different driver states, such as fatigue, sleepiness, stress, inattention and impairing emotions, employing existing and novel sensing technologies, taking into account traffic and weather conditions via V2X and personalizing them to individual drivers physiology and driving behaviour. In addition, the core development includes multimodal and adaptive warning and intervention strategies based on current driver state and severity of scenarios. The final outcome is the successful fusion of the developed elements into an integrated driver/rider state monitoring system, able to both be utilized in and be supported by vehicle automation of Levels 1 to 4. The system will be validated with a wide pool of drivers/riders under simulated and real road conditions and under different driver/rider states; with the use of 2 cars (1 conventional, 1 electric), 1 truck, 2 PTWs and 1 bus demonstrators. This challenging task has been undertaken by a multidisciplinary Consortium of 30 Partners, including an OEM per vehicle type and 7 Tier 1 suppliers.
