ISO 22840:2010 for extended-range backing aids (ERBA) addresses light-duty vehicles [e.g. passenger cars, pick-up trucks, light vans and sport utility vehicles (motorcycles excluded)] equipped with such ERBA systems. ISO 22840:2010 establishes minimum functionality requirements that the driver can expect of the system, such as the detection of and information on the presence of relevant obstacles within a defined detection range. ISO 22840:2010 also sets minimum requirements for failure indication as well as performance test procedures. ISO 22840:2010 includes rules for the general information strategy but does not restrict the kind of information or display system. ERBA systems are intended to provide backing aid functionality over an extended area located aft of the subject vehicle. ERBA systems are not intended for short-range detection of obstacles located immediately behind the vehicle. If a short-range detection system is needed, either in lieu of or in addition to an ERBA system, reference can be made to ISO 17386. ISO 22840:2010 does not include reversing aids and obstacle-detection devices for use on heavy commercial vehicles. Requirements for those systems are defined in ISO/TR 12155. ISO 22840:2010 does not include visibility-enhancement systems, such as video-camera aids that do not have distance ranging and warning capabilities. ERBA systems use object-detection devices (sensors) for detection and ranging in order to provide the driver with information based on the distance to obstacles. The sensing technology is not addressed; however, technology does affect the performance test procedures defined in ISO 22840:2010. The test objects are defined based on systems using ultrasonic and radar sensors, which are the most commonly used detection technology for long-range applications at the time of publication of ISO 22840:2010. ERBA systems are intended to supplement the interior and exterior rear view mirrors, not eliminate the requirement for such mirrors. Automatic actions (e.g. applying brakes to prevent a collision between the subject vehicle and the obstacle) are not addressed in ISO 22840:2010. Responsibility for the safe operation of the vehicle remains with the driver. ERBA systems calculate a dynamic estimate of collision danger (e.g. perhaps using a time-to-collision algorithm) and warn the driver that immediate attention is required in order to avoid colliding with the detected obstacle. A dynamic warning is necessary for the higher vehicle speeds that occur in backing events where the relative closing velocities between the vehicle and the obstacle are greater as compared to low-speed situations, such as parking. The purpose of this dynamic warning is to deliver a more urgent warning to the driver in order for the driver to take timely action. Distance indications are optional, but if so included, it is recommended that reference be made to ISO 15008 for requirements.
Abstract
Overview
ISO 22840:2010 - Intelligent transport systems - Devices to aid reverse manoeuvres - Extended-range backing aid systems (ERBA) - defines minimum functional and performance requirements for ERBA systems fitted to light‑duty vehicles (passenger cars, pick‑ups, light vans, SUVs). The standard specifies the expected detection capabilities, warning behaviour, failure indications and test procedures for systems that provide backing‑aid information across an extended area behind the vehicle (1.0 m to 5.0 m aft of the rear bumper).
Key topics and technical requirements
- Detection range: ERBA systems shall monitor a defined zone of regard from 1.0 m to 5.0 m behind the rear bumper. Short‑range detection (<1.0 m) is outside this standard (see ISO 17386).
- Detection performance: Minimum detection and warning performance levels are specified across sub‑areas of the zone (near, edge, far, side and out), with quantitative acceptance criteria and statistical thresholds.
- Closing speed & dynamic warning: Systems must handle backing closing speeds up to and beyond about 3.0 m/s and provide a dynamic warning (e.g., time‑to‑collision based) that escalates urgency as collision risk increases.
- Latency and responsiveness: Defined response‑time limits and start‑up readiness indications are required so the driver receives timely information.
- Driver interface & information strategy: The standard sets rules for how presence and dynamic warnings are presented (visual, audible, tactile), but does not mandate specific HMI designs. Distance readouts are optional; if provided, ISO 15008 is recommended for visual presentation requirements.
- Sensors & test objects: Sensing technology (radar, ultrasonic, etc.) is not prescribed, but test objects and test procedures are defined primarily for ultrasonic and radar systems.
- Reliability & failures: Self‑test capabilities and failure indication requirements ensure drivers are informed if the ERBA is not operational.
- Limitations: ERBA is intended to supplement interior/exterior mirrors, not replace them, and is not intended to reliably detect pedestrians or to perform automatic vehicle control (e.g., automatic braking).
Applications and users
ERBA systems are used to assist drivers during mid‑ to higher‑speed backing manoeuvres (longer reverse travel than parking). Primary users of ISO 22840:2010:
- Vehicle manufacturers integrating ERBA into new models
- Tier‑1/Tier‑2 suppliers of radar/ultrasonic backing sensors and ECUs
- HMI designers implementing in‑vehicle warnings
- Test labs performing performance and conformity testing
- Regulators and fleet operators specifying safety requirements
