Target vehicle for ADAS testing

A two-wheeled target vehicle to mount onto an Advanced Driver Assistance System (ADAS) testing platform, the two-wheeled target vehicle being arranged to simulate a tilt of a two-wheeled vehicle during cornering, the two-wheeled target vehicle comprising:

• a sensor arranged to measure a parameter relating to dynamics of the two-wheeled target vehicle as the two-wheeled target vehicle is moved by the ADAS testing platform;
• an actuation assembly arranged to adjust a tilt of a tiltable body of the two-wheeled target vehicle relative to a base of the two-wheeled target vehicle, the actuation assembly comprising:
• a rotary actuator, the rotary actuator being oriented along a fore-aft direction of the two-wheeled target vehicle,
• a pinion driven by the rotary actuator,
• a rack, wherein the rack is a toothed belt, the toothed belt being fastened at either end to the base at respective end fixings, and
• two idler gears mounted on lateral arms extending from the tiltable body,
• wherein the pinion is engaged with the rack, and the rack runs around the two idler gears, such that rotation of the pinion moves the pinion and the two idler gears along the rack, relative to the end fixings,
• to tilt the tiltable body;
• and
• a control unit configured to control the actuation assembly to adopt a simulation tilt angle, a magnitude of the simulation tilt angle being dependent on an output of the sensor,
• wherein the sensor, control unit, and actuation assembly are self-contained within the two-wheeled target vehicle and are independent of the ADAS testing platform to which the two-wheeled target vehicle is mounted.

An assembly to tilt a target vehicle, the assembly comprising:

• a sensor to attach to the target vehicle to measure a parameter relating to dynamics of the target vehicle;
• an actuation assembly arranged to adjust a tilt of a tiltable body of the target vehicle relative to a base of the target vehicle, the tilt being in dependence on an output of the sensor, the actuation assembly comprising:
• a rotary actuator, the rotary actuator being oriented along a fore-aft direction of the target vehicle,
• a pinion driven by the rotary actuator,
• a rack, wherein the rack is a toothed belt, the toothed belt being fastened at either end to the base at respective end fixings, and
• two idler gears mounted on lateral arms extending from the tiltable body,
• wherein the pinion is engaged with the rack, and the rack runs around the two idler gears, such that rotation of the pinion moves the pinion and the two idler gears along the rack, relative to the end fixings,
• to tilt the tiltable body;
• and
• a control unit configured to control the actuation assembly to adopt a simulation tilt angle, a magnitude of the simulation tilt angle being dependent on an output of the sensor.

A method of modeling a Vulnerable Road User (VRU) for Advanced Driver Assistance System (ADAS) testing using a target vehicle mounted on a moveable testing platform, the method comprising:

• measuring a parameter relating to dynamics of the target vehicle;
• and
• adjusting a tilt of a tiltable body of the target vehicle relative to a base of the target vehicle using an actuation assembly, the tilt being in dependence on an output of a sensor,
• wherein the actuation assembly comprises:
• a rotary actuator, the rotary actuator being oriented along a fore-aft direction of the target vehicle,
• a pinion driven by the rotary actuator,
• a rack, wherein the rack is a toothed belt, the toothed belt being fastened at either end to the base at respective end fixings, and
• two idler gears mounted on lateral arms extending from the tiltable body,
• wherein the pinion is engaged with the rack, and the rack runs around the two idler gears, such that rotation of the pinion moves the pinion and the two idler gears along the rack, relative to the end fixings, to tilt the tiltable body, and
• wherein the measuring the parameter and adjusting the tilt are conducted remotely from the moveable testing platform.
