and share experiences on ECE Regulation implementation with a continuing support from many Meeting on UN/ECE R13H, Braking for Passenger Vehicles . Regulation No H of the Economic Commission for Europe of the United Nations (UN/ECE) — Uniform provisions concerning the approval of passenger cars. ECE Regulation 90 (abbreviated “ECE R90”) is an ECE Regulation specifying design, construction, and performance requirements and test protocols for.

Generation r13g a braking signal to illuminate stop lamps. Test conditions Test vehicle loading condition: The full deceleration must be reached within the timeframe of 2.
In hydraulic-transmission braking systems, the filling ports of the fluid r13hh shall ecee readily accessible; in addition, the receptacles containing the reserve fluid shall be so designed and constructed that the level of the reserve fluid can be easily checked without the receptacles having to be opened, and the minimum total reservoir capacity is equivalent to the fluid displacement resulting when all the wheel cylinders or calliper pistons serviced by the reservoirs move from a new lining, fully retracted position to a fully worn, fully applied position.
The maximum value r13hh the vehicle deceleration is determined from the “maF curve” and is named as “amax”. Would you like to keep them? Alternatively, for vehicles with battery r113h electric traction only, the state of charge may be adjusted by running the vehicle.
The effectiveness of the linkage between the control of the service braking system and the different components of the transmission systems shall not be liable to diminish after a certain period of use. Alternative measuring methods to those referred to in paragraph 2. The final drive ratios; 2. To eliminate the effects of differential brake temperatures it is recommended that z AL be determined prior to the determination of k.

This requirement shall apply for all conditions of loading when compensation exceeds the following limits: General performance characteristics for category “B” and category “C” BAS systems When an emergency condition has been sensed, at least by a very fast application of the pedal, the BAS system shall raise the pressure to deliver the maximum achievable braking rate or cause full cycling of the ABS.
The steering wheel velocity data is then filtered with a moving 0,1 second running f13h filter. The combination performance shall be verified by calculations referring to the maximum braking performance actually achieved by the motor vehicle alone laden during the Type-0 test with the engine disconnected, using the following formula no practical tests with a coupled unbraked trailer are required:.
The test vehicle is driven around a circle 30 meters in diameter at a speed that produces a lateral acceleration of approximately 0,5 to 0,6 g for three clockwise laps followed by three anticlockwise laps. This diagram supports the explanation provided under paragraph 3. Sine with Dwell test of oversteer intervention and responsiveness. A sampling rate for data acquisition of at least Hz is required.
Preparation of analogue signals includes consideration of filter amplitude attenuation and sampling rate to avoid aliasing errors, and filter phase lags and time delays. Upon completion of the two series of test runs, post processing of yaw rate and lateral acceleration data is done as specified in paragraph 5. This test is conducted on a road test surface affording good adhesion. Example of test 2 of a category “B” BAS system 5.
This annex defines the special requirements for documentation, fault strategy and verification with respect to the safety aspects of Complex Electronic Vehicle Control Systems definition 2. The maximum design speed; 2.
At one-half the sampling rate i. The vehicle is allowed to cool-down between each test runs for a period of 1,5 to 5 minutes, r31h the vehicle stationary. If the chosen provision selects a partial performance mode of operation under certain fault conditions, then these conditions shall be stated and the resulting limits of effectiveness defined.

If, when tested to the procedure specified above, and at vehicle braking rates between 0,15 and 0,8 the vehicle meets one of the following criteria, then it passes this wheel lockup sequence requirement:. It shall not be possible to disconnect, partially or totally, one part of the service braking system other than by automatic means. Only torque output values obtained from data collected when the vehicle deceleration is within the range of 0,15 g to 0,80 g are used in the regression analysis.
Procedure for monitoring the state of battery charge.
Non-specified faults or other information shall be indicated only by the flashing of the warning signal. Brake disc and drums 2.
A steering robot programmed to execute the required steering pattern shall be used in paragraphs 5. In the case of a braking system according to paragraph 5.
