A vehicle control arrangement is configured to control steering and velocity of a road vehicle including a velocity control arrangement, remote sensors configured to acquire vehicle surrounding information, a steering control unit configured to control steering of the vehicle based on the vehicle surrounding information, an upcoming road geometry detecting unit configured to detect presence of an upcoming curve section, a hands-on-wheel detecting unit configured to detect if presence exists of at least one hand on a steering wheel of the vehicle. The velocity control arrangement is configured to perform a reduction of velocity of the vehicle in case presence of an upcoming curve section is detected and no presence is detected of at least one hand on the steering wheel.

Vehicle control arrangement, road vehicle and method of controlling a road vehicle

A safety stoppage device and method for safety stoppage of an autonomous vehicle including control networks and sensors for monitoring the autonomous vehicle surroundings and motion includes a brake-control unit for a brake system including wheel brakes of the autonomous vehicle, and a signaling processing system for processing sensor signals enabling an autonomous drive mode thereof. Where a drivable space exists is predicted based on data from the sensors and sensor fusion, and a safe trajectory to a stop within the drivable space is calculated and sent to the brake-control unit and stored therein. The brake-control unit is shielded against electromagnetic compatibility problems and configured to monitor if the control networks are operational and, if determined incapacitated, control the autonomous vehicle to follow the most recently calculated safe trajectory to a stop within the drivable space using differential braking of the wheel brakes thereof in order to effectuate steering.

Safety stoppage device and method for safety stoppage of an autonomous vehicle

A vehicle sensor diagnosis system and method, and a vehicle including such a system are provided. The vehicle sensor diagnosis system is configured to predict upcoming vehicle surrounding conditions along at least a section of a host vehicle route based on database information on the host vehicle surroundings along the section and information on a current host vehicle surrounding, estimate an expected level of sensor performance for the route section based on the prediction, assess the level of sensor performance detected during host vehicle travel along the host vehicle route section, assess if a difference between the estimated level of sensor performance and the detected level of sensor performance for the host vehicle route section exceeds a first threshold difference and, if so, initiate a diagnose result communication.

Vehicle sensor diagnosis system and method and a vehicle comprising such a system

A device and method for safety stoppage of an autonomous road vehicle having a localization system and sensors for monitoring the vehicle surroundings and motion, and a signal processing system for processing sensor signals enabling an autonomous drive mode. A processor continuously predicts where a drivable space exists, calculates and stores a safe trajectory to a stop within the drivable space, determines a current traffic situation, and determines any disturbances in sensor data, vehicle systems or components enabling the autonomous drive mode. If an incapacitating disturbance is determined, a request for a driver to take control is signaled and it is determined if the driver has assumed control. If not, the vehicle is controlled to follow the most recent safe trajectory to a stop in a safe stoppage maneuver during which, or after, one or more risk mitigation actions adapted to the determined current traffic situation are performed.

A vehicle, vehicle system and method for increasing at least one of safety and comfort during autonomous driving is provided. The vehicle system includes an autonomous drive arrangement with multiple sensors, a vehicle control arrangement and a positioning system. The vehicle system is configured to determine an estimated probability that at least one sensor will become unavailable, or an estimated time/distance ahead until at least one sensor is determined to become unavailable. The vehicle system is further configured to activate at least one countermeasure based on at least one of the estimated probability, the estimated time and the estimated distance.

Vehicle, vehicle system and method for increasing safety and/or comfort during autonomous driving

Provided are a method and an apparatus for prediction of time available for autonomous driving, in a vehicle having autonomous driving capabilities and including at least one remote sensor configured to acquire vehicle surrounding information and at least one vehicle dynamics sensor configured to determine vehicle dynamics parameters. The method and apparatus include at least one of a positioning arrangement that provides map data with associated information, a route planning arrangement that enables route planning, and a real time information acquiring arrangement that acquires at least one of real time traffic information and real time weather information. The time available is calculated based on a planned route and at least one of vehicle surrounding information, vehicle dynamics parameters, map data with associated information, real time traffic information and real time weather information, for the planned route. The calculated time is output to a human machine interface in a vehicle.

A method for transition between driving modes of a vehicle is disclosed. The driving modes include an autonomous driving (AD) mode, a partly autonomous driving (PAD) mode and a manual driving (MD) mode. A transition from the PAD mode to the AD mode is performed by enabling the AD mode. A transition from the AD mode to the PAD mode is performed by releasing a steering wheel lock when the PAD mode is in an enabled state. A transition from the MD mode to the AD mode is performed by enabling the AD mode. A transition from the AD mode to the MD mode is performed by releasing the steering wheel lock when the PAD mode is in a disabled state. A system for performing the method and a vehicle including the system are also disclosed.

A system and method for collision warning in a host vehicle including: detecting a collision risk between the host vehicle and an other user of the road with a detection means based on input from at least one sensor which detects at least one parameter related to the other user of the road with respect to the host vehicle; identifying possible options to avoid a collision between the host vehicle and the other user of the road based on input from the detection means, wherein possible options for the host vehicle to avoid a collision are identified as well as possible options for the other user of the road to avoid a collision are identified; calculating among the identified possible options at least one preferred avoidance action in order to avoid a collision between the host vehicle and the other user of the road; and if the at least one preferred avoidance action involves at least one possible option identified for the other user of the road, then generating a warning signal from the host vehicle in a direction towards the other user of the road in order to warn the other user of the road of the collision risk.
