Definitions
- the invention relates to a method for emergency stopping of a motor vehicle according to the preamble of claim 1 .
- the invention relates also to a system for emergency stopping of a motor vehicle.
- the invention also relates to a motor vehicle. It also relates to a computer programme and a computer programme product.
- US20080252466 describes methods and systems which are activated when a driver is suddenly no longer able to operate the vehicle. Emergency lights may switch on, the signal horn may sound and the vehicle may come to a halt. This process may be assisted inter alia by cameras and radar.
- DE10201 1 109618 describes a method for automatically being able to stop a vehicle when the driver is no longer capable of doing so. This process may be assisted by navigation systems.
- One object of the present invention is to propose a method and system for emergency stopping which enables improved safety.
- SUMMARY OF THE INVENTION This and other objects indicated by the description set out below are achieved by a method and a system and by a motor vehicle, computer programme and computer programme product of the kinds indicated in the introduction which further present the features indicated in the characterising parts of the attached independent claims. Preferred embodiments of the method and the system are defined in the attached dependent claims.
- the invention achieves the objects with a method for emergency stopping of a motor vehicle comprising the steps of determining the driver's ability to operate the vehicle in a controlled way and, when driver inability is determined, of activating a vehicle-controlled emergency stop of the vehicle, further comprising the step of automatically controlling the vehicle's retardation and its path during the retardation according to a vehicle-adapted emergency stop process for ensuring safe braking of the vehicle.
- This safe braking of the vehicle improves safety both for the surroundings and for any passengers, e.g. standing passengers on board the vehicle. It also improves safety by preventing the vehicle, e.g. a tank truck, from overturning.
- the step of controlling the emergency stop process comprises taking into account a passenger perspective which takes passenger safety considerations into account. Passenger safety is thus improved.
- the method further comprises the step of determining existing passenger distribution and passenger situations in the vehicle as a basis for control of the emergency stop process. Taking into account passenger distribution such as where in the vehicle, e.g. a bus, the passengers are, and for passenger situations in terms of whether a passenger is standing, sitting, sitting in a wheelchair, lying in a pram or the like, makes it possible for the operation of the vehicle during the emergency stop process to be automatically adapted to passenger situations, thereby affording passengers greater safety and also comfort.
- the method further comprises the step of assessing expected passenger distribution and passenger situations in the vehicle, based on a model for behaviour of a certain passenger population, as a basis for control of the emergency stop process. This makes it possible for the operation of the vehicle during the emergency stop process to be adapted to passenger distribution and passenger situations, thereby affording passengers greater safety and also comfort.
- the method comprises the step of controlling the emergency stop process on the basis of necessary changes in direction and speed while taking into account passenger safety considerations.
- the vehicle's operation may thus be optimised while taking passenger presence into account, although in cases where there are no passengers or only sitting passengers, passenger safety and comfort need not be prioritised as much, since in such cases the vehicle may be operated according to another emergency stop process whereby it is for example possible, with a view to saving time, for the vehicle's speed to be higher and its retardation and turning more severe without affecting passenger safety or comfort.
- the step of automatically controlling the vehicle's retardation and its path during the retardation according to a vehicle-adapted emergency stop process involves taking factors pertaining to the world around into account. Taking such factors into account, e.g. obstacles, other road users such as other vehicles, pedestrians etc. and the nature of the terrain along vehicle's path such as safety barriers, possible dips or slopes and the like further improves safety.
- the invention achieves the objects with a system for emergency stopping of a motor vehicle comprising means for determining the driver's ability to operate the vehicle in a controlled way, and means, when driver inability is determined, for activating a vehicle-controlled emergency stop of the vehicle, comprising means for automatically controlling the vehicle's retardation and its path during the retardation according to a vehicle-adapted emergency stop process for ensuring safe braking of the vehicle.
- the means for controlling the emergency stop process comprises taking into account a passenger perspective which takes passenger safety considerations into account.
- system comprises means for determining existing passenger distribution and passenger situations in the vehicle as a basis for control of the emergency stop process.
- system further comprises means for assessing expected passenger distribution and passenger situations in the vehicle, based on a model for behaviour of a certain passenger population, as a basis for control of the emergency stop process.
- system comprises means for controlling the emergency stop process on the basis of necessary changes in direction and speed while taking into account passenger safety considerations.
- the means for automatically controlling the vehicle's retardation and its path during the retardation according to a vehicle-adapted emergency stop process involves taking factors pertaining to the world around into account.
- the embodiments for the system present similar advantages to corresponding embodiments for the method mentioned above.
