Yamaha R1 Series 2015 User Manual

FEATURES
1-9
The “Track” mode displays information needed in racing. The tachometer displays the over-8,000 rpm
to redline range used most often in racing with a high degree of clarity and detail. This mode features
high priority displays of lap number, lap times as well as a stopwatch function, all useful items for racing.
Each display also has a memory function that enables lap-by-lap time verification for quick post-race
analysis.
6-axis “IMU” for 3-dimensional detection of machine motion
This model adopts the 6-axis Inertial Measurement Unit (IMU). It consists of three gyro sensor (angular
velocity sensor) that measures machine pitch “a”, roll “b” and yaw “c”, and three G-sensor (accelerom-
eter) that measures acceleration in the forward-backward, up-down and right-left directions.
The signals from each sensor and a machine-speed sensor made it possible for high-precision detec-
tion of machine lean angle and rear wheel slide.
The information on running machine attitude provided by the IMU is sent to the engine control unit
(ECU) via CAN (Controller Area Network) transmission to enable real-time calculations that are then
reflected to provide optimum engine output. Engine control is conducted through the integration and
adjustment of the commands from the various controls systems (TCS and the other systems explained
below) to supplement the control mapping for (1) fuel injection volume, (2) ignition timing and (3) throttle
valve opening.
Five control systems to effectively bring out the machine’s high potential
The engine control unit (ECU) of the new model is programmed to actuate five different control systems
in order to heighten competitiveness in actual race conditions.
Each of the systems is designed to let the rider adjust the level of control, or turn each system On or Off.
